Abstract
The present invention discloses a structure of exhausting air in a microwave oven, which comprises an air channel which is arranged on the upper part of a cavity body. The air channel exhausts circulating air in the microwave oven; exhaust fan components are arranged on the back end of the air channel to make air flow; a plurality of safe supporting columns are arranged on air pipes which are arranged on the front parts of the exhaust fan components and are positioned with the exhaust fan components with definite distance; the safe supporting columns and the air channel are together formed into an entirety by injection moulding. The present invention has the structure that user's hands which enter the microwave oven through the air channel to carry out the replacing operation of a filter can be blocked by the safe supporting columns to prevent the hands from touching the exhaust fan components which are used for making the air flow generated, and therefore, the present invention can prevent the user from being injured.
Description
Technical field
The invention relates to micro-wave oven, particularly be the exhaust structure of micro-wave oven.In order to prevent that the user is subjected to the injury of exhaust fan assembly.
Background technology
Fig. 1 is the exploded perspective view of known hood type microwave oven structure, and Fig. 2 is the part oblique view of known hood type microwave oven user mode.As shown in Figure 1, hood type microwave oven is arranged on the top of gas furnace.When utilizing gas furnace to cook, hood type microwave oven absorbs the air that contains heat and moisture that produces, and it is discharged to outside function.
Be provided with the air duct of guiding stove inner circulating air on the top of this microwave oven cavity 1, air duct comprises the baffle plate 12,13 of both sides, and baffle plate 12,13 forms integral body by the synthetic resin injection moulding, is installed on the middle position of top board 15.
Rear side at air duct 10 is provided with the exhaust fan assembly 20 that produces air stream.Here, the exhaust fan assembly sucks air from the side, and discharges air to the place ahead of micro-wave oven.
The air flow process that exhaust fan assembly 20 causes is as follows: when 20 runnings of exhaust fan assembly, the air that contains heat and moisture that produces in the gas furnace of micro-wave oven downside flows into micro-wave oven inside by the air entry that is arranged on the micro-wave oven bottom surface.
Flow into the air of micro-wave oven inside, flow to exhaust fan assembly 20 through air flow passage.Afterwards, flow to the air of exhaust fan assembly 20, output to again in the exhaust passage in the place ahead.
According to the position and the direction of exhaust fan assembly 20, discharge directions both may be towards the place ahead of micro-wave oven, also may be towards the top of micro-wave oven.
Fig. 2 forms rectangular exhaust outlet 42 on the cavity front panel 40 of air duct 10 front ends.Be discharged to the air of air duct 10 by exhaust fan assembly 20, output to the outside of micro-wave oven by the exhaust outlet 42 of air duct 10 front ends.
The filter of removing foreign matter is set on air duct 10.But filter needs to change on time, need carry out more changing jobs of filter from exhaust outlet 42.
As above the micro-wave oven of Gou Chenging has following problem: as shown in Figure 2, the user is by exhaust outlet 42, and when carrying out the replacing operation of filter, because the rotation of the high speed of scavenger fan assembly 20, the user is easy to injured.
Summary of the invention
In order to solve the problem that above-mentioned technology exists, the invention provides the micro-wave oven exhaust structure of the injured safety of a kind of user of preventing.
To achieve these goals, the technical solution used in the present invention is: the exhaust structure of micro-wave oven comprises air duct, exhaust fan assembly, described air duct be arranged on cavity above, forwards discharge the circulating air in the micro-wave oven; Described exhaust fan assembly is arranged on the rear end of air duct, produces air stream; It is characterized in that a plurality of safety jacks are arranged on the air duct in exhaust fan assembly the place ahead, with the exhaust fan assembly at a distance of certain distance.
Described safety jack forms integral body with the air duct injection moulding.
The invention has the beneficial effects as follows: among the present invention who constitutes by above structure, even user's hand enters in the micro-wave oven by the exhaust outlet of air duct, when carrying out the replacing operation of filter, also can be blocked by safety jack, prevent that thus hand from running in micro-wave oven the exhaust fan assembly that produces air stream, thereby can prevent the user injured.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: Fig. 3 is the STRUCTURE DECOMPOSITION oblique view of the embodiment of micro-wave oven exhaust structure of the present invention.As seen from the figure, on top board 15 middle positions on cavity 1 top, the air duct 10 of the circulating air in the guiding micro-wave oven is set.
Flow into the air that contains heat and moisture of micro-wave oven inside from gas furnace,, flow to exhaust fan assembly 20 by the air flow passage of micro-wave oven inside.Then, output to the air of exhaust fan assembly 20, flow in the air duct 10 in the place ahead.
On the cavity front panel 40 of air duct 10 front ends, be provided with to the outside rectangular exhaust outlet 42 of discharging air of micro-wave oven.
On the air duct in exhaust fan assembly 20 the place aheads, be provided with a plurality of safety jacks 50 that the hand that prevents the user is run into exhaust fan assembly 20.When the user carries out the replacing operation of filter, prevent that hand from running into exhaust fan assembly 20, safety jack 50 should be located at a distance of exhaust fan assembly 20 certain distance, on the position in exhaust fan assembly 20 the place aheads.
In order to improve security, length that should corresponding exhaust fan assembly 20 from left to right is arranged in order safety jack 50 is set.In an embodiment, though 3 safety jacks are set, concrete quantity and the position of being provided with, according to exhaust fan assembly 20 and air duct 10 position and specification be set, change to some extent.
In the present embodiment, safety jack 50 protrudes in the upside of cavity by certain height, and considers the convenience of cavity installing engineering, forms with air duct 10 injection mouldings.
Though the safety jack 50 of present embodiment has adopted cylinder type, this is also unrestricted, and its size and shape can change.
The place ahead at safety jack 50 is provided with filter, removes the foreign matter that contains in the moving air in the air duct 10.
Below, the effect of micro-wave oven exhaust structure of the present invention is described: when starting micro-wave oven, 20 runnings of exhaust fan assembly, and produce air stream.In the gas furnace of micro-wave oven bottom, the heat content of generation and the air of moisture are inhaled into the inside of micro-wave oven by the suction of exhaust fan assembly 20, flow in the air duct 10 in exhaust fan assembly 20 the place aheads.
Air from exhaust fan assembly 20 is discharged through air duct 10, is discharged to the outside of micro-wave oven by exhaust outlet 42.In this process, utilize the filter that is provided with in the air duct 10, remove foreign matter.
After micro-wave oven uses a period of time, need to change the filter in the air duct 10, and when changing filter, the user reaches in the air duct 10 of micro-wave oven the filter that more renews by exhaust outlet 42.At this moment, user's hand is subjected to the restriction of safety jack 50, can not run into exhaust fan assembly 20, thereby can prevent that the user's is injured.
Major technology guiding theory of the present invention is, in air duct, have at a distance of exhaust fan assembly 20 on the position of certain distance safety jack 50 is set, thus the user more renew filter the time, prevent that hand from running into exhaust fan assembly 20, thereby the prevention user is injured.
