BACKGROUND AND PRIOR ART:
[002] Most mixer-grinders use a fan to suck in the air and cool the motor. The direction of the air flow can be from bottom to top or vice-versa. The path of the air is not controlled which leads to inefficient cooling of the motor and other regions of high temperature. Managing the audible noise that is carried out by the 10 flowing air is also difficult as there is no feature to channelize the air towards one direction.
[003] Publication No. 20170055775 (D1) discloses a hand mixer having a detection mechanism for discriminating between beaters and other rotating accessories. The operation of the mixer may be altered depending on the type of 15 accessory that is detected. D1 provides an air inlet that is located behind the beaters, the inlet co-operating with an internal air channel that provides a flow of air to an intake fan located in a front area of the housing. The air vent opening comprises one or a pair of horizontal slots located along a lower margin of the mixer body. Air enters the vent and from there enters a horizontal and internal 20 channel that leads into the intake opening of an electric fan that is mounted on a horizontal axis. Preferably, the fan is located adjacent to the front of the mixer body, directing air rearwardly for the purpose of cooling the beater's gearing arrangement, the electric motor and the mixer's electrical circuitry and processor. Air is ejected from the rear vents located on the flat rear surface or heel of the 25 mixer. However, guides are provided for air flow at the inlet only.

An air channel and an air inlet opening are additionally arranged between the gear ring and the grinding body in the grinding machine.

[0022] The figures depict embodiments of the present subject matter for the purposes of illustration only. A person skilled in the art will easily recognize from the following description that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles 15 of the disclosure described herein.
DESCRIPTION OF THE PREFERRED EMBODIMENTS:
[0023] The present invention will be described in detail below with reference to an embodiment as shown in the drawing.
[0024] Accordingly the present invention provides a closed volume (duct) (12) 20 around a motor (13) and fan (14) assembly in domestic mixer-grinders is used to reduce the peak temperatures of the motor under heavy usage conditions. Said duct (12) also comprises a guiding structure (15) to cool the high temperature rise part of said motor (13). According to the present invention, said duct (12) is covered by a visco-elastic (acoustic) material and the body of the domestic mixer-25 grinders to reduce the audible noise and vibration under different operating conditions such as different motor speeds and load under which said mixing grinding appliance is subjected to.
7
[0025] Referring to the figure 1 and figure 2, an air channelization system (10) along with visco-elastic material (11) for mixing grinding appliance having a duct (12) to encompass the motor (13) and fan (14) assembly into a close volume is disclosed.
[0026] Said air channelization system (10) forces the air to flow efficiently over 5 said motor (13) which leads to the temperature reduction of said motor (13). An air guiding structure (15) is provided inside said duct (12) to direct the air flow towards a commutator (16). Said commutator (16) has the maximum temperature while said mixing grinding appliance is in operation.
[0027] Said air guiding structure (15) guides the airflow from an air inlet (17) to 10 an air outlet (18) through within said duct (12) and in the region of high temperature as opposed to a generic flow of air. Said air guiding structure (15) is a curved structure which results in a better and efficient airflow. Both the configurations of air flow (bottom to top as shown in figure 1 and vice-versa as shown in figure 2) are tested and found to provide similar benefits. The flow lines 15 shown in the figures are only for representative purpose.
[0028] Further, as the vibrations of said motor (13) are transmitted through its mounting, the gap between the duct (12) and the mixer body is filled with visco-elastic (acoustic) material (11) leading to reduction in audible noise. This also results in significant reduction in peak motor temperatures (usually the 20 commutator is where the peak occurs) are between the old designs and the channelized design with visco-elastic material (11) according to the present invention. Said visco-elastic material (11) is chosen from polyurethane, foam or similar materials..
25
[0029] The duct (12) also guides the air flow towards one direction making it easier to manage the audible noise by using noise reduction devices such as silencer and/or muffler. In fact significant reduction is observed between the old and new design in terms dB of audible noise.
8
[0030] By guiding the flow of air in a channelized manner, the amount of air flow can be optimized leading to lower audible noise.
[0031] Advantage of the invention-
1) Air flow required for cooling of the motor is reduced,
2) Motor can be run for a longer duration, and 5
3) Overall lower audible noise.
