Referring to fig. 1, fig. 2 and fig. 3, the present invention provides a host 10 applied to a food processor 100.
In an embodiment of the present invention, the main frame 10 includes a main frame housing 11, a motor 13, and an air duct 15; the host housing 11 has an accommodating cavity 111, and a host air inlet 113 and a host air outlet 115 communicating with the accommodating cavity 111; the motor 13 is arranged in the accommodating cavity 111; the air duct 15 is disposed in the accommodating chamber 111 and sleeved outside the motor 13, the air duct 15 has an air duct inlet end 151 and an air duct outlet end 153 communicated with the accommodating chamber 111, an air duct inlet 1511 is formed between the air duct inlet end 151 and an outer wall surface of the motor 13, the air duct inlet 1511 is annularly disposed, and a distance D between an inner wall surface of the air duct inlet end 151 and the outer wall surface of the motor 13 is1The range values of (A) are: d is not less than 1mm1≤4mm。
In an embodiment of the present invention, the main housing 11 is mainly used to form a receiving cavity 111 for receiving and installing the components such as the motor 13 and the air duct 15, so as to prevent the components from being exposed to the outside and being easily damaged. The main air inlet 113 and the main air outlet 115 are mainly used for cooling air to pass through the inside of the main unit 10, so as to perform heat exchange and cooling on the inside of the main unit 10. In order to avoid the influence of the cooling air exhausted from the host outlet 115 on the user, the host outlet 115 may be disposed on a side of the host housing 11 where a control panel (not shown) is not disposed. In order to increase the intake of the cooling air, the main housing 11 may be provided with two or more main intake vents 113, which are respectively located at the sides of the main housing 11. The air duct 15 has a guiding and gathering effect on the cooling air, so that a large amount of cooling air is ensured to flow through the motor 13 and exchange heat with the motor 13, and the heat dissipation effect on the motor 13 is improved. Referring to fig. 7, it can be seen that when the inner wall surface of the air inlet end 151 of the air duct is connected to the outer wall surface of the motor 13A distance D between1Range value D of1If the air volume is less than 1mm, the air volume of the cooling air entering the air duct 15 from the air duct air inlet 1511 is smaller, so that the heat which can be taken away by the cooling air to the motor 13 is smaller, and the heat exchange effect of the cooling air to the motor 13 is influenced; when the distance D between the inner wall surface of the wind barrel inlet end 151 and the outer wall surface of the motor 131Range value D of1When the diameter is larger than 4mm, the air speed of the cooling air entering the air duct 15 from the air duct air inlet 1511 is small, so that the heat exchange efficiency of the cooling air on the motor 13 is slow, and the heat exchange effect of the cooling air on the motor 13 is influenced; when the distance D between the inner wall surface of the wind barrel inlet end 151 and the outer wall surface of the motor 131The temperature of the motor 13 is lower than 2mm, that is, the heat dissipation effect of the cooling air on the motor 13 reaches a peak value. Therefore, the distance D between the inner wall surface of the wind barrel inlet end 151 and the outer wall surface of the motor 13 is set1The range values of (1) are set as: d is not less than 1mm1Not more than 4mm, namely, a certain amount of cooling air is ensured to enter the air duct 15, and the cooling air has a certain air speed, so that the heat dissipation effect of the cooling air on the motor 13 is improved. Wherein, the distance D between the inner wall surface of the wind barrel inlet end 151 and the outer wall surface of the motor 131The value of (b) may be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, etc., and may be any value within the above range. In addition, the projection of the air duct 15 may be a circular structure, and certainly, the projection may also be a square structure, so as to ensure that the projection is matched with the shape of the motor 13, which is not limited in the present application.
When the main unit 10 of the technical scheme of the invention dissipates heat, cooling air enters the accommodating cavity 111 of the main unit shell 11 through the main unit air inlet 113 and enters the air guide cylinder 15 through the air inlet end 151 of the air cylinder communicated with the accommodating cavity 111. So that the cooling air can exchange heat with the motor 13 in the air duct 15 for cooling and take away heat generated by the motor 13 during operation. And then enters the accommodating cavity 111 through the air outlet end 153 of the air duct communicated with the accommodating cavity 111, and is discharged from the air outlet 115 of the host machine. Thus, the continuous and timely heat dissipation of the motor 13 in the main machine 10 is completed, so that the heat dissipation effect of the motor 13 is improved, and the service life of the food processor 100 is prolonged. In addition, because the inner wall surface of the air inlet end 151 of the air cylinder is arranged between the outer wall surface of the motor 13Distance D of1The range values of (A) are: d is not less than 1mm1Less than or equal to 4mm, thus avoiding the distance D between the inner wall surface of the air inlet end 151 of the air duct and the outer wall surface of the motor 131If the air quantity is too small, the air quantity of cooling air entering the air duct 15 from the air duct air inlet 1511 is too small, and the heat exchange and cooling effect on the motor 13 is affected; also avoids the distance D between the inner wall surface of the wind barrel air inlet end 151 and the outer wall surface of the motor 131Too big, lead to the velocity of flow that cooling air got into in the air duct 15 from dryer air intake 1511 undersize and influence the heat transfer cooling effect to motor 13 to further improved the radiating effect to motor 13, prolonged cooking machine 100's life.
Referring to fig. 4 and fig. 5, in an embodiment of the present invention, the motor 13 includes a stator 131, a rotor 133 and a carbon brush 135, the rotor 133 is rotatably disposed through the stator 131, and the carbon brush 135 is disposed on a side peripheral surface of the stator 131 facing the air duct 15 and electrically connected to the rotor 133; the main unit 10 further includes a filling member 17, the filling member 17 is disposed at the air inlet end 151 of the air duct and is disposed corresponding to the carbon brush 135, and a distance D between a surface of the filling member 17 facing the stator 131 and an outer wall surface of the stator 1312The range values of (A) are: d is not less than 0mm2≤4mm。
It can be understood that, since the carbon brush 135 is protruded from the outer wall surface of the stator 131, the distance between a part of the inner wall surface of the wind inlet end 151 of the wind barrel and the outer wall surface of the motor 13 may be relatively large. In this case, the filler 17 is provided between the both, and the gap between the both can be reduced so that the cooling wind entering the air guide duct 15 has a constant wind speed. Referring to fig. 7, a distance D between a surface of the filling member 17 facing the stator 131 and an outer wall surface of the stator 1312The temperature of the motor 13 is lower when the value of (a) is set to a smaller value, that is, the heat radiation effect of the cooling air on the motor 13 can be improved. The distance D between the surface of the filler 17 facing the stator 131 and the outer wall surface of the stator 1312The range values of (1) are set as: d is not less than 0mm2Not more than 4mm, can effectually guarantee the packing effect of packing 17 to avoid the dryer air inlet end 151 to correspond the distance between the internal wall face of the position of carbon brush 135 and the outer wall face of motor 13 too big, influence the wind speed of cooling air. Wherein the surface of the filler 17 facing the stator 131A distance D from an outer wall surface of the stator 1312The value of (b) may be 0mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, etc., and may be any value within the above range. Furthermore, the distance D between the inner wall surface of the wind inlet end 151 of the wind barrel and the outer wall surface of the motor 13 is explained1The value of (b) may be a distance between an inner wall surface of the duct inlet end 151 and an outer wall surface of a housing of the motor 13, or may be a distance between an inner wall surface of the duct inlet end 151 and an outer wall surface of the stator 131 of the motor 13.
In an embodiment of the invention, the air duct 15 has an avoiding groove (not shown) at the air inlet end 151 of the air duct, the avoiding groove (not shown) is disposed corresponding to the carbon brush 135 for the carbon brush 135 to pass through and be accommodated in the air duct 15, and the filling member 17 is embedded in the avoiding groove (not shown).
It can be understood that the shape of the air duct 15 and the shape of the motor 13 can be more fitted by the arrangement of the avoiding groove (not shown), and the distance D between the inner wall surface of the air inlet end 151 of the air duct and the outer wall surface of the motor 13 is ensured1The value of (D) is less than or equal to 1mm1The range of less than or equal to 4mm so as to improve the cooling effect of the cooling air on the motor 13 positioned in the air duct 15.
In an embodiment of the present invention, the filling member 17 is an elastic member or a sound absorbing member.
It will be appreciated that when the filler member 17 is an elastic member, for example: rubber or silicone. Because it has certain elasticity to can cushion the vibration that motor 13 produced at the during operation, reach the shock attenuation to motor 13. When the filler 17 is a sound absorbing member, for example: acoustic wool or polyurethane foam. Because the sound energy can be partially converted into heat energy, the noise generated when the motor 13 works can be absorbed, and the noise of the motor 13 is reduced. In addition, the filler 17 may be connected to the air duct 15 by a bolt, may be connected to the air duct 15 by a snap, or may be bonded to the air duct 15 by glue, which is not limited in this application, and it is sufficient to ensure that the filler 17 is stably connected to the air duct 15.
Referring to fig. 4 and fig. 6, in an embodiment of the invention, the host 10 further includes a fan 19, the fan 19 is disposed in the accommodating cavity 111, the fan 19 has a fan inlet 19a and a fan outlet 19c, the air outlet 153 of the air duct forms an air duct outlet 1531, the fan inlet 19a is communicated with the air duct outlet 1531, and the fan outlet 19c is communicated with the host outlet 115.
It can be understood that the fan 19 can improve the fluidity of the cooling air in the air duct 15, and drive the cooling air to enter from the air duct inlet and exit from the air duct outlet 1531 in order. Because the fan 19 and the motor 13 are independently arranged, the fan 19 can work no matter the motor 13 is in a working state or a non-working state, and the heat dissipation effect of the motor 13 is further improved.
In an embodiment of the present invention, the fan 19 includes a volute 191 and an impeller 193, the volute 191 is disposed in the accommodating chamber 111 and is located at a lower end of the air outlet end 153 of the wind barrel, and the impeller 193 is rotatably disposed in the volute 191; the volute 191 includes an upper casing plate 1911, a lower casing plate 1913, and a casing side plate 1915 connecting the upper casing plate 1911 and the lower casing plate 1913, the casing side plate 1915 is provided with a fan outlet 19c, and the upper casing plate 1911 is provided with a fan inlet 19 a.
It is understood that the scroll 191 is provided to guide the cooling air introduced from the fan inlet 19a to the impeller 193, and to collect the cooling air sent from the impeller 193 in the scroll 191 while converting a part of the dynamic pressure into the static pressure, and to guide the cooling air to the fan outlet 19 c. Thus, the fluidity of the cooling air can be increased, and the heat exchange efficiency is improved; meanwhile, the noise generated when the fan 19 works is reduced, and the working environment is improved. And the volute 191 is positioned at the lower end of the air outlet end 153 of the air duct, so that smooth flow of cooling air from top to bottom is ensured, the change times of the flow path of the cooling air can be reduced, and the flowability of the cooling air is further improved.
Referring to fig. 3, in an embodiment of the present invention, the fan inlet 19a is disposed in a circular shape and is coaxial with the impeller 193, and the diameter D of the fan inlet 19a3And impeller 193 diameter D4The ratio range value of (A) is: 1/3 is not less than D3/D4≤1。
It can be understood that the fan inlet 19a is circularly formed so that the cooling air is distributed everywhereAnd uniformly enters the volute 191, thereby ensuring the flow stability of the cooling air. And the fan 19 is arranged coaxially with the impeller 193, so that the cooling air is reduced to generate backflow, and the air inlet efficiency of the fan 19 is improved. In addition, the diameter D of the fan inlet 19a3And impeller 193 diameter D4The range of values of the ratio of (a) is set as: 1/3 is not less than D3/D4Less than or equal to 1. The small air inlet quantity of the fan 19 caused by the over-small air inlet 19a of the fan can be avoided; meanwhile, the problem that the air inlet speed of the fan 19 is low due to the fact that the air inlet 19a of the fan is too large can be avoided, and therefore the air inlet effect of the fan 19 is guaranteed. Wherein, the diameter D of the fan inlet 19a3And impeller 193 diameter D4Ratio D of3/D4The values may be 1/3, 1/2, 1, etc., and may be any values in the above range.
