This application is capable of embodiments in many different forms and is intended to cover by those skilled in the art the embodiments disclosed herein and the equivalents thereof without departing from the spirit and scope of the present application.
In the present application, a motor arrangement and a scrubber are provided, respectively, and attention is paid to the detailed description in the following embodiments.
The motor device configuration when carrying out the during operation in burnisher, can satisfy normal work, can avoid external steam to get into the motor again, cause the problem of erosion to the motor, combine figure 1, figure 2, figure 3 below to carry out the detailed introduction to the motor device of this first embodiment of this application.
As shown in fig. 1, which is a schematic structural diagram of a motor apparatus according to a first embodiment of the present application, the motor apparatus includes: a housing 101 and a motor body 102.
A motor accommodating cavity 104 and a main air duct 103 are further arranged inside the casing 101, and the motor body 102 is arranged in the motor accommodating cavity 104.
The wall surface of the motor accommodating cavity 104 separates the motor accommodating cavity 104 from the main air duct 103, and the main air duct 103 is disposed between the outer wall surface of the motor accommodating cavity 104 and the inner wall surface of the housing. Specifically, the main air duct is concave inside the shell.
The front end of the motor is provided with a suction impeller 105, the suction impeller 105 is connected to a rotating shaft 1022 at the front end of the motor, an air inlet 1031 of the main air duct is located on the side surface of the suction impeller 105, and an air outlet 1032 of the main air duct is located on the side wall surface of the housing 101.
The casing 101 is provided with a front end inlet 1011 at a position corresponding to the air suction impeller 105, when the air suction impeller 105 works, the air suction end of the air suction impeller 105 sucks external air from the front end inlet 1011 and leads the external air out through the main air duct 103, and an air outlet of the main air duct is positioned on the side wall surface of the casing.
The suction impeller 105 provided in this embodiment is a generic term of a wheel disc and rotating blades mounted on the wheel disc, and when the motor 102 works, the suction impeller 105 is driven to rotate, and air enters the inside of the housing 101 along with the rotation of the suction impeller 105, specifically, the air is thrown out from two ends of the suction impeller 105 along with the rotation of the suction impeller 105, enters the main air duct 103 from the air inlet 1031 of the main air duct, and is finally discharged from the air outlet 1032 of the main air duct.
The main air duct 103 is a main air duct when the motor device cooperates with the cleaning device, for example: in the floor cleaning machine, the motor device can cooperate and hold the bucket and accomplish the dehumidification work on ground, and the bottom that holds the bucket can set up corresponding dehumidification instrument, and at the floor cleaning machine during operation, impeller 105 that breathes in can inhale and hold the air in the bucket, holds the inside negative pressure that produces of bucket, makes the dehumidification instrument that holds the bottom of the barrel portion setting dehumidifies ground or wall body in the effect of negative pressure, when the impeller that breathes in absorbs the bucket air and dehumidify, inevitable steam that still can inhale in the bucket, impeller inspiratory steam and air of breathing in can follow the main air duct is discharged motor device.
It should be noted that the shape design of the main air duct described above is only one preferred embodiment of the present embodiment, and in other embodiments, different structures may be adopted, for example: one side wall surface of the motor accommodating cavity can be used as the side wall surface of the shell, and the main air duct is in an L shape inside the shell, which belongs to the simple transformation of the structure of the motor device in the first embodiment of the application, does not deviate from the core of the application, and is within the protection range of the application.
The above process introduces the working process of the main air duct of the present application, and in order to solve the heat dissipation problem of the motor, the key of the present application is also the design of the heat dissipation air duct and the structural relationship between the heat dissipation air duct and the main air duct 103 and the motor accommodating cavity 104. Traditional motor device, motor heat dissipation needs independent cooling fan, and the shortcoming of design like this is that motor device's own volume grow, and the space that needs to occupy also grows along with it, is unsuitable to be installed on the equipment that extremely harsher to the space requirement, for example: it is not suitable for mounting on a hand-held cleaner. The application provides a main thinking in heat dissipation wind channel is: the motor accommodating cavity 104 and the front end of the air suction impeller 105 are communicated, the air suction end of the air suction impeller 105 generates a negative pressure principle by means of rotation of the air suction impeller 105, and the air suction dehumidification function and the heat dissipation function of the motor body of the motor device are considered.
It should be noted that the following design of the heat dissipation air duct of the motor device is only one preferred embodiment of the present application, and is a further improvement of the motor device of the present application, and the heat dissipation air duct is designed to dissipate heat of the motor, and the heat dissipation air duct is not needed to be designed if the motor itself has a cooling function or the housing of the motor device has a heat dissipation function.
The heat dissipation air duct provided by the present embodiment is formed by the internal structure of the housing 101 and the structure of the motor body 102.
The heat dissipation air duct is a channel which is connected with the air suction end of the air suction impeller from the top of the motor device.
The housing 101 is provided with an air inlet 106 at a position located at the rear end of the motor accommodating cavity 104.
The heat dissipation air duct functions to guide the cooling air entering from the air inlet 106 through a gap between the stator and the rotor of the motor body 102, and to flow toward the air suction end of the air suction impeller located at the front end of the air suction impeller, while avoiding the main air duct. The air suction end of the air suction impeller corresponds to the front end inlet 1011, and when the motor works normally, hot air emitted by the motor flows to the air suction end of the air suction impeller along with the cooling air.
The stator and the rotor are parts of the motor, the rotor specifically refers to a rotating shaft 1022 of the motor, and the stator refers to a stator core and magnetic steel of the motor. In the motor, the stator surrounds the rotor, and after the motor is electrified, a magnetic field wrapping the rotor is formed inside the stator, the rotor is driven to rotate under the action of the magnetic field force, and the motor starts to work. The heat generated by the motor is mainly generated by the relative movement of the stator and the rotor.
In order to avoid the influence of the size of the air inlet 106 on the overall heat dissipation of the device, the motor device is further provided with an air conditioning accommodating cavity 108, and the air conditioning accommodating cavity 108 is formed by the inner wall surface of the shell provided with the air inlet 106 and the gap between the motor accommodating cavities 104. The cool air receiving chamber 108 receives cool air introduced from the air inlet 106.
In addition, in order to make the cooling air smoothly enter the motor accommodating cavity 104, a ventilation gap is provided between the cooling air accommodating cavity 108 and the motor accommodating cavity 104, and the cooling air enters the motor accommodating cavity 104 through the ventilation gap.
When guaranteeing that cooling air can get into motor holding chamber 104 smoothly, still need to guarantee that the heat of the production of motor 102 work can flow out motor holding chamber 104, consequently, this embodiment the heat dissipation wind channel still include guide air duct 107, guide air duct 107's income wind gap 1071 sets up the side wall face of motor holding chamber 104, guide air duct 107 by income wind gap 1071 extends to the intermediate layer that casing 101 internal face set up, the intermediate layer is a part of guide air duct 107, the intermediate layer along casing internal face extends to the end of breathing in of impeller, guide air duct 107 and main air duct 103 are separated through the intermediate layer wall of intermediate layer.
Because the air guide duct 107 extends to the air suction end of the air suction impeller, and the air suction end of the air suction impeller corresponds to the front end inlet 1011, the heat dissipation air duct starts from the air inlet 106, passes through the cold air accommodating cavity 108 and the motor accommodating cavity 104, and finally forms a channel connecting the air inlet 106 and the front end inlet 1011 through the air guide duct 107. The motor 102 operates to drive the air suction impeller 105 to rotate, so as to suck air and water vapor through the front end inlet 1011, and simultaneously suck hot air generated by the motor in the motor accommodating cavity 104 and cooling air entering from the air inlet 106.
It can be seen that the core principle of heat dissipation of the motor device provided in the first embodiment of the present application is to absorb the hot air emitted from the motor 102 through the suction impeller 105, and simultaneously to suck the external cooling air from the air inlet 106 under the action of the negative pressure generated at the suction end of the suction impeller. In addition, when the motor device is designed, in order to ensure that cooling air can smoothly enter the motor accommodating cavity 104, the wall surface connecting the motor accommodating cavity 104 and the cold air accommodating cavity 108 may be designed to be mesh-shaped, or the structure of the cold air accommodating cavity 108 and the cold air inlet 106 is no longer adopted, and the rear end wall surface of the motor accommodating cavity 104 is directly designed to be mesh-shaped to replace a corresponding shell.
It should be noted that the design of the air guide duct 107 in the heat dissipation duct is only one preferred embodiment of the present device, and different structures may be adopted in other embodiments. For example: the air guide duct 107 may not be provided with an interlayer in the housing, as long as the air guide duct communicates the motor accommodating cavity 104 with the air suction end of the air suction impeller, and the air guide duct 107 is separated from the main air duct 103, so that the heat dissipation of the motor can be realized according to the above principle no matter what structure the air guide duct 107 adopts. These are simple variations of the main air duct and the heat dissipation air duct described in the first embodiment of the present application, and do not depart from the core of the present application, and all of them are within the protection scope of the present application.
In order to more clearly illustrate the heat dissipation process and the heat dissipation principle of the motor apparatus provided in this embodiment, the working process of heat dissipation of the motor apparatus is described in detail with reference to fig. 2 and 3 on the basis of the above structure.
Fig. 2 is a schematic view illustrating a flow direction of air in a heat dissipation duct according to a first embodiment of the present application.
When the motor device works normally, the air suction impeller 105 arranged at the front end of the motor is driven by the motor 102 to suck air through the air suction end of the air suction impeller, and the front end inlet 1011 generates negative pressure, because the drainage air duct 107 comprises an interlayer arranged in the shell and extending to the air suction end of the air suction impeller along the inner wall surface of the shell, and the heat dissipation air duct is communicated with the outer part of the shell corresponding to the air inlet 106 and the air suction end of the air suction impeller, under the influence of the negative pressure, the air suction impeller 105 sucks in external air corresponding to the front end inlet 1011, and simultaneously sucks external cooling air through the air inlet 106 to enter the heat dissipation air duct, and after the cooling air enters the heat dissipation air duct, hot air generated by the motor 102 in the motor accommodating cavity 104 flows to the air suction impeller 105 together through a gap between a stator and a rotor of the motor body 102, into the main air duct 103.
Fig. 3 is a schematic view illustrating the air flow direction of the main air duct according to the first embodiment of the present application.
When the motor device works in cooperation with a cleaning device, the main air duct 103 is through the air suction impeller 105 sucks external air and water vapor, and of course, the main air duct 103 also can suck hot air in the heat dissipation air duct through the air suction impeller 105, specifically, the hot air generated in the heat dissipation air duct enters the main air duct 103 and then can be discharged along with the external sucked air and water vapor from the air outlet 1032 of the main air duct.
In order to prevent external water vapor from entering the interior of the motor to corrode the motor body in the traditional design scheme, the common method is to seal or arrange a labyrinth passage surrounding the rotating shaft of the motor only by a bearing.
Firstly, in practical application, the effect of directly adopting bearing sealing is not good, and a large amount of water vapor still directly enters the motor. Secondly, the labyrinth passage is a plurality of sequentially arranged annular sealing teeth arranged around the rotating shaft, and a series of closure gaps and expansion cavities are formed among the teeth. Although the design that adopts labyrinth passageway can reach isolated steam's purpose to a certain extent, labyrinth passageway itself is a passageway that has the clearance, and can drive in order to guarantee motor shaft the impeller that breathes in normally rotates, can have appropriate clearance between motor holding chamber and the motor shaft also, adopts labyrinth passageway still can't avoid steam to get into the inside problem that causes the erosion to the motor body of motor completely. In the scheme of this application first embodiment, in order to solve the inside problem of above-mentioned steam entering motor, adopt the design of solid-state grease layer. The solid grease layer 1041 is disposed on an inner side wall of the motor accommodating cavity at the front end of the motor body and surrounds the motor rotating shaft 1022.
When the motor operates, grease can be adsorbed on the surface of the rotating shaft to form an oil film, and the oil film can effectively seal a gap between the motor rotating shaft 1022 and the motor accommodating cavity 104, so that water vapor is prevented from entering the motor accommodating cavity 104 to corrode the motor body 102.
Preferably, a bracket for fixing the motor in the motor accommodating cavity is arranged on the inner wall surface of the motor accommodating cavity.
The support includes an upper skeleton 1042, a lower skeleton 1043, and an upper support 1044.
The upper frame 1042 and the lower frame 1043 are sequentially disposed on the side wall surface of the motor accommodating cavity 104, a distance between the upper frame 1042 and the lower frame 1043 is the same as a length of a stator protruding from a side surface of the motor, and the stator protruding from the side surface of the motor 102 is installed between the upper frame 1042 and the lower frame 1043.
The upper support 1044 is disposed on a rear end wall surface of the motor accommodating cavity 104, a shape of the inner wall surface of the upper support 1044 is the same as a shape of a rear end of the motor, and the rear end of the motor 102 is fixed in the motor accommodating cavity 104 through the upper support 1044.
In summary, the motor device provided in the first embodiment of the present application has the main air duct independent of the motor accommodating cavity for discharging the external water vapor and air sucked by the suction impeller, and the problem that the water vapor directly enters the motor to corrode the motor and affect the operation of the motor is avoided. Simultaneously, in order not to influence the motor heat dissipation, the inside heat dissipation wind channel that still is provided with of casing, the steam that the motor produced flows to under the guide in heat dissipation wind channel the impeller of breathing in discharges through the main air duct, and the motor device that this application provided utilizes the impeller 105's the principle that the tip of breathing in produced the negative pressure, compromises the dehumidification function and the heat dissipation function of breathing in of motor device, has abandoned among the prior art the impeller inspiratory steam of breathing in directly get into the motor inside problem that causes the erosion to the motor body, has still solved the radiating problem of motor simultaneously. In addition, the heat dissipation of the motor device only depends on the structure of the motor device, and the motor device does not depend on an independent heat dissipation fan any more, so that the vibration and the noise generated when the motor device normally works are reduced, the user experience is improved, and meanwhile, the manufacturing cost of the motor device is also saved.
