Description
Technical field
The present invention relates to a kind of centrifugal fan for garbage disposer, relate in particular to a kind of technical field of family expenses centrifugal fan for garbage disposer.
Technical background
In developed country, for the purpose of environmental protection, the domestic food rubbish in the city generally all will carry out resolution process before abandoning, and as a kind of energy-saving refuse disposal installation (notification number CN1140359C), it comprises the shell with an intakeport and a relief opening; It is interior to deposit a container of exemplary food waste to be installed in said shell, and said container has a suction port and air outlet; Be formed at an input channel of said external container in said shell, it is to extend to said suction port to introduce ozone in said container by said intakeport; In said shell, be formed at a discharge route of said external container, it is extended to said shell by said air outlet relief opening to discharge because the air that contains horrible smell that the decomposition of exemplary food waste produces in said container; One odor removal, it comprises decomposes the catalyzer that is included in said horrible smell in the exhausting air, in order to activate a heater of said catalyzer, reaches a housing of placing said catalyzer and said heater; Said odor removal wherein is installed in said discharge route, cause the outer surface of said housing to be exposed in the said input channel, and in said input channel, fresh air must be decomposed to strengthen said exemplary food waste by said heater heats by contacting with the outer surface of said housing.Above-mentioned refuse disposal installation is equipped with blower fan in the pipeline of the discharge route of the party upstream of odor removal, deliver to odor removal with the air-flow that will contain horrible smell.Because the Environmental Conditions of the refuse disposal installation in the such scheme is in family environment, therefore, the installation of blower fan in refuse disposal installation must be reliable, otherwise will produce bigger vibration and noise in the fan operation process, brings interference to Environmental Conditions.
Summary of the invention
The object of the invention is to provide a kind of blower fan that can guarantee reliably to install, give vibration and the less centrifugal fan for garbage disposer of noise that brings in the fan operation, problems such as it is relatively poor to have solved the blower fan installation reliability that the conventional garbage processor exists, and vibration and noise be bigger in the running.
Above-mentioned technical purpose of the present invention mainly solves by the following technical programs: it comprises mounting plate and is arranged on the bellows of mounting plate one side, be provided with wind wheel in the cavity that mounting plate and bellows surround, the opposite side of mounting plate is provided with motor, Motor Shaft passes mounting plate and wind wheel is in transmission connection, described mounting plate comprises mounting plate body and assembly department, mounting plate body and assembly department are structure as a whole and by a bending angle transition, sector becomes external corner position and inner corner trim position, the external corner position punching press of described knuckle forms some depressions, correspondingly forms some projectioies at the inner corner trim position of knuckle.Wherein, form depression at the external corner position of the knuckle of mounting plate body and assembly department and form projection at the inner corner trim position, played the effect that is similar to stiffening rib, make the knuckle of mounting plate body and assembly department have enough intensity, thereby blower fan is installed on the garbage disposer by the assembly department of mounting plate, can avoid rocking between assembly department and the mounting plate body, guaranteed the installation reliability of blower fan, thereby reduced the vibration in the fan operation process, reduced the noise in the garbage disposer operation process; In addition, mounting plate of the present invention only needs punching press to machine, and processes comparatively simply, and can not increase cost of material.
As preferably, described depression is the wedge shape that drift angle is an acute angle, and correspondingly described projection also is the wedge shape that drift angle is an acute angle, thereby makes the knuckle of first portion and second portion possess enough intensity.
As preferably, the described external corner position that several are recessed in knuckle equidistantly distributes, thereby makes knuckle intensity unanimity everywhere.
As preferably, the knuckle of described mounting plate body and assembly department is 90 ° of angles, has further improved the intensity of the mounting plate body and the knuckle between the assembly department of mounting plate, has guaranteed the reliability that blower fan is installed.
As preferably, described assembly department is provided with several mounting holes, be provided with a shock reducing structure with center hole in the described mounting hole, described shock reducing structure is by the last laminar body at two ends and following laminar body and be connected laminar body and the Cylindrical object of following laminar body constitutes, and describedly goes up the mounting hole two ends that laminar body and following laminar body lay respectively at described assembly department.The present invention adopts two ends all to have the shock reducing structure structure of laminar body, during installation, mounting screw or bolt pass from the center hole of shock reducing structure, make and do not take place directly to contact between the assembly department of screw or bolt and mounting plate, separate by shock reducing structure between the two, blower fan issuable vibrations in operation process will be absorbed by shock reducing structure, and can not be delivered on the shell of garbage disposer, thereby improved the damping effect of blower fan greatly, and reduced the noise that produces because of vibrations.
As preferably, the last laminar body of described shock reducing structure and following laminar body are disk shape structure, and the external diameter of the described external diameter of going up laminar body and described following laminar body is all greater than the aperture of the mounting hole of described assembly department.
