Abstract
The invention relates to a range hood. The range hood (1) comprises a draught fan assembly (2) and a motor assembly (3). The draught fan assembly (2) comprises an impeller (21) and a volute (22) used for containing the impeller (21). A motor (31) comprises a motor body (311) and a shaft rod (310). The motor assembly (3) comprises a motor hood (32). The motor hood (32) at least partially covers the motor body (311), so that the motor body (311) is isolated from the space defined by the volute (22) when the range hood (1) is in an operating state. According to the technical scheme, the motor body is isolated from water vapor and oil smoke in the space defined by the volute, and the surface of the motor body can be kept clean for a long term; and accordingly, the service life of the motor can be prolonged, and the high exhaust and suction efficiency of the range hood is guaranteed.
Description
[technical field]
The present invention relates to household appliance technical field, refer in particular to a kind of range hood for purifying kitchen environment.
[background technology]
Range hood generally comprises blower fan and for driving the motor of blower fan.The blower fan of existing range hood and motor are the most not
Detachable, blower fan or motor can not disassemble individually from range hood, thus, it is impossible to it is individually replaced and keeps in repair electricity
Machine or impeller.Parts within impeller, spiral case are also difficult to clean up.
In general, flue gas enters back into the spiral case for containing impeller after the drainage screen of range hood, and flue gas is by filtering
It is filtered the oils and fats being partially contained in flue gas during net, even if so, in space defined in spiral case, still has oil smoke and steam,
And motor is chronically exposed in this environment, the service life of motor can be affected, because steam or oil smoke easily enter motor internal and make
Become the damage of parts.Further, since motor and blower fan can not be split, the greasy dirt of motor surface accumulation is not easily cleaned, day
The long-pending moon tires out, and the greasy dirt of these accumulations can affect the performance of motor and then affect the pumping efficiency of range hood.
[summary of the invention]
It is an object of the invention to, at least one technical problem above, it is provided that the range hood of a kind of improvement.
For reaching above-mentioned technical purpose, the present invention proposes a kind of following technical scheme: a kind of range hood, including blower fan assembly
And motor assembly, described blower fan assembly includes impeller and for containing the spiral case of described impeller, and described motor assembly includes for driving
The motor of dynamic described impeller, wherein, described motor includes that motor body and axostylus axostyle, described motor assembly also include motor cover, institute
State motor cover and cover described motor body at least in part so that described motor body under the running status of described range hood with
Space defined in described spiral case is isolated.
Technical scheme makes the steam in space defined in motor body and spiral case, oil smoke be isolated, and can keep for a long time
Motor body clean surface, thus the service life of motor can be extended, and ensure that range hood has efficient pumping efficiency.
Wherein, " described motor cover covers described motor body at least in part " is it should be appreciated that it includes that motor cover itself can
The situation making space defined in motor body and spiral case be isolated, also includes that motor cover and other respective outer side edges make motor body
With spiral case defined in the situation that is isolated of space.The motor cover of the first situation can be to include two parts, the two part
Motor body can be encapsulated in its inner space.The most semi-enclosed uncovered cover of motor cover of second case, by motor body cover
On a platy structure.
In a kind of possible embodiment of the present invention, described motor is detachably connected with described impeller, makes described blower fan assembly
It is detachable with described motor assembly.It has the benefit that and on the one hand can not dismantle motor, not move oil suction
In the case of cigarette owner's body portion, carry out blower fan assembly dismounting, clean, change and other adjust.On the other hand, can not be subject to
Impeller, spiral case and physical dimension thereof and the restriction of design, carry out freely the dismantling of motor assembly, keep in repair, upgrade and maintenance etc..
Manufacturing enterprise is facilitated to carry out product platform management and the installation of after-sale service and maintenance according to different consumers.
In a kind of possible embodiment of the present invention, described impeller includes that axostylus axostyle set, described axostylus axostyle are used for being plugged to described axostylus axostyle
Overlap to connect described impeller and described motor.Thus facilitate described motor and the fractionation of described impeller and connection.
In a kind of possible embodiment of the present invention, described range hood includes the shell for loading described spiral case and backboard,
Under described running status, described backboard and described shell fit together；Described motor assembly is fixed on described backboard, institute
State spiral case to be just installed in described shell before described shell and described backboard assemble.Such architectural feature is had the advantage that,
In the case of other parts of range hood are motionless, the shell being provided with spiral case can be separated backboard, thus by blower fan from oil suction
Disassemble on cigarette machine；Or the backboard being fixed with motor is disassembled from range hood.
In a kind of possible embodiment of the present invention, under the described running status of described range hood, described shell and described
Backboard forms a top and the cuboid of bottom opening.
In a kind of possible embodiment of the present invention, described motor cover provides an envelope together with described backboard for described motor body
Close space.Motor body thus is isolated with outside oil smoke, water vapour environment in described closing space.
In a kind of possible embodiment of the present invention, described motor cover is bowl-shape, frustum-like shape or hemispherical.These shapes are easy
In processing and manufacturing, it suitably processes the through hole passed for described axostylus axostyle.
In a kind of possible embodiment of the present invention, described shell has at least one towards its internal prominent protuberance, described
Described spiral case is fixed in described shell by protuberance against described spiral case thus described protuberance.The benefit improved further carried out
It is, on the premise of not increasing cost, to utilize the protuberance formed to become reinforcement, the intensity of housing integration structure can be improved；
Protuberance may be used to directly be fixed in shell by spiral case；Or, protuberance is in order to be fixed on spiral case auxiliary in shell, then passes through spiral shell
Nail securely by fixing for spiral case in the enclosure, it is seen that before making to be screwed, spiral case by protuberance auxiliary positioning in target position
Putting, protuberance plays effective positioning action.The protuberance of described shell is against described spiral case, thus with its straight inwall directly supports
Existing shell by spiral case is compared, and improved shell volume is big, and the beneficially flowing of air-flow, air intake resistance is little, to fume-exhausting
The improvement of the noise of machine is helpful.
In a kind of possible embodiment of the present invention, described shell has at least two protuberance, and described at least two protuberance is respectively
It is positioned on the surface that described shell is symmetrical.Thus, this improvement can balancedly improve the intensity of housing integration structure, and by spiral case
Preferably it is fixed in shell, prevents spiral case unbalance stress from easily dropping in shell.
In a kind of possible embodiment of the present invention, the cross section of described protuberance is strip, rectangle or arc.
