Detailed description of the invention
With specific embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings, but not as the limit to the present invention
Fixed.
Microwave-oven-heating process needs and outside air circulation, but considers to be arranged on fixing relative closure space, therefore,
Need to be designed the circulation path of circulation air required in furnace chamber, to solve the air intake problem of built-in microwave oven.
As shown in Figures 1 to 6, the micro-wave oven in the present invention includes doorframe 1 and covers the panel 4 on doorframe outer surface,
Meeting the needs of furnace chamber inner circulating air to realize air intake, the present invention is formed with air intake passage on doorframe.
After micro-wave oven start work in the present invention, cooling fan band moving air flow is heater members cooling, final hot gas
Stream discharges microwave oven system by louvre.Owing to micro-wave oven embeds cabinet, relative closure, extraneous air is by above-mentioned air intake
Passage, under external and internal pressure difference effect, air inlet sucks air.Air intake passage is the entrance of the inside and outside air-flow of conducting, and air flows into
Air inlet structure, the space circulation between cabinet and the housing of micro-wave oven, under cooling fan effect, enter micro-wave oven.
In a preferred embodiment, doorframe 1 is offered ventilation slot 2 and through hole 3.Wherein, ventilation slot 2 is along doorframe 1
Outer surface extend, through hole 3 then extends along the thickness direction of doorframe 1, so that ventilation slot 2 and through hole 3 are orthogonal two
Individual side upwardly extends, and makes one end of ventilation slot 2 connect with through hole 3.
In order to form air intake passage, panel 4 is arranged on the outer surface of doorframe 1 by the present invention, and so, panel 4 covers
On ventilation slot 2 and through hole 3, thus between panel 4 and doorframe 1, form air intake passage.
For example, as it is shown in figure 1, the air of outside can by this air intake passage enter along the direction shown in arrow A and B into
In wind passage, flow to the rear of doorframe 1 then along the direction of arrow C or D, thus along between the housing and cabinet of micro-wave oven
Gap flow to the rear of micro-wave oven, and finally enter in furnace chamber, it is thus possible to the circulation air needed for micro-wave oven is provided, thus protects
Card use of microwave ovens performance, has the feature of simple in construction, low cost, is particularly well-suited to built-in microwave oven.
Relative on doorframe 1 have for fire door is installed opening 5 for, in the embodiment shown in fig. 3, ventilation slot 2
The other end arrange towards the inside of opening 5, so, the direction of the interior by opening 5 for the air-flow enters in ventilation slot 2.
More specifically, the entrance of air intake passage is preferably placed on the end face towards described opening 5 of described doorframe 1, so, face can be passed through
The outside of ventilation slot 2 and through hole 3 is entirely all covered up by plate 4, thus achieve in the front of micro-wave oven to ventilation slot 2 and
Whole air intake passage is completely hidden in the lower section of panel 4 by hiding of through hole 3, not only ensure that the complete and beautiful of outward appearance, and
And make surface be more prone to cleaning.
For example, the size of panel 4 and cabinet perforate is equivalently-sized, after installation, the edge laminating cabinet of panel 4
Inwall, the outer surface of panel 4 and cabinet flush with outer surface.From external observation, door frame surface is smooth attractive in appearance, and cleaning surface is very square
Just.
Opening 5 in the present invention is rectangular, its have successively head and the tail connect top, the first vertical edge, the second vertical edge and under
Limit.Wherein, doorframe 1 can form above-mentioned ventilation slot 2 and through hole 3 respectively on the first vertical edge and/or following corresponding framework.
It is highly preferred that the first vertical edge is positioned at the side of the control panel 6 away from micro-wave oven of opening.
Preferably, horizontally extending with the ventilation slot 2 in the first corresponding framework of vertical edge, with following corresponding framework
On ventilation slot 2 vertically extend, thus between left side and lower lateral micro-wave oven and cabinet gap provide circulation sky
Gas.
Preferably, doorframe 1 be formed with multiple ventilation slot 2 on the first vertical edge and/or following corresponding framework, each lead to
Wind groove 2 all connects with one or more through holes 3.Preferably, through hole 3 or ventilation slot 2 can be rectangular.For example, shown in Fig. 3
In embodiment, be provided with three through holes differing in size 3 in the side of the first vertical edge, each through hole 3 all accordingly with two or
Three horizontally disposed ventilation slots 2 connect；In following side, being then provided with four through holes 3 abreast, each through hole 3 also divides
Do not connect with at least one ventilation slot 2.
Present invention also offers a kind of micro-wave oven, particularly a kind of built-in microwave oven, it includes above-mentioned micro-wave oven
Air inlet structure.
Certainly, it is above the preferred embodiment of the present invention.It should be pointed out that, for those skilled in the art
For, on the premise of without departing from its general principles, some improvements and modifications can also be made, these improvements and modifications are also
It is considered as protection scope of the present invention.
