Specific embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from start to finish
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and be not considered as limiting the invention.
Below with reference to the accompanying drawings describing micro-wave oven according to embodiments of the present invention in detail.
As shown in Figures 1 to 7, micro-wave oven according to embodiments of the present invention, including：Body of heater 10, baffle plate 20 and changeover module
30.
Specifically, with cooking cavity 11 and control chamber 12 in body of heater 10.Wherein, there is connection on the side wall of control chamber 12
The first through hole 121 of cooking cavity 11.It is understood that cooking cavity 11 is used for cooking food, control chamber 12 is used for installing microwave
The electric components such as the aobvious control plate of stove, controller.In addition, " side wall " here should make narrow sense understanding, cooking cavity 11 and control is refered in particular to
That side wall that chamber 12 shares.
Baffle plate 20 is movably located on the side wall of control chamber 12.Changeover module 30 be located on body of heater 10 and with 20 phase of baffle plate
Even.Changeover module 30 can make baffle plate 20 in the primary importance (as shown in Figure 4 and Figure 5) for closing first through hole 121 and open
Changeable between the second place (as shown in Figure 6 and Figure 7) of first through hole 121.
Micro-wave oven according to embodiments of the present invention, by changeover module make baffle plate close first through hole primary importance with
And open changeable between the second place of first through hole, first through hole can be opened and closed as needed, and then prevent water
Vapour enters control chamber to cause damage to the electric component in control chamber with high-temperature gas.
More specifically, according to an example of the present invention, the upper end of baffle plate 20 has and is suitable to be upward through control chamber 12
The lead 201 of roof.
Changeover module 30 includes：Elastic component 31, electromagnet 32 and screw 33.
The elastic component 31 of such as spring is socketed on lead 201.(arrow i.e. as shown in Figure 4 under elastic component 31
Direction indicated by down) hold upper (i.e. indicated on arrow as shown in Figure 4 direction) against baffle plate 20 to hold and elastic component
31 upper end against control chamber 12 roof often to promote downwards the baffle plate in the primary importance, i.e., baffle plate 20 closes the
The position of one through hole 121.
Electromagnet 32 is fixedly installed on the roof of control chamber 12 and is connected with the upper end of lead 201.Advantageously, electromagnetism
Iron 32 is fixedly installed on the upper surface of the roof of control chamber 12.Further, electromagnet 32 is fixedly installed on by screw 33
On the upper surface of the roof of control chamber 12.
As shown in Figure 6 and Figure 7, when electromagnet 32 is in "on" position, electromagnet 32 overcome the elastic force of elastic component 31 with
Baffle plate 20 is made to open the position of first through hole 121 in the second place, i.e. baffle plate 20.
As shown in Figure 4 and Figure 5, when electromagnet 32 is in power failure state, baffle plate 20 is in the work of the restoring force of elastic component 31
With lower in primary importance.
It is understood that electromagnet 32 is suitable to electrically connect with the controller of micro-wave oven.When microwave oven cooking food, control
Device processed can open or cut out first through hole 121 by comparing the pressure reduction of cooking cavity 11 and control chamber 12 determining baffle plate 20.
That is, when microwave oven cooking food and when radiator fan is opened, now the pressure in cooking cavity 11 is less than control chamber 12
Interior pressure, the steam produced in cooking cavity 11 and high-temperature gas will not be entered in control chamber 12 via first through hole 121.This
When, baffle plate 20 both may be at primary importance, it is also possible in the second place.
And when microwave oven cooking food and radiator fan closing, now the pressure in cooking cavity 11 is more than in control chamber 12
Pressure, the controller of micro-wave oven can control 32 dead electricity of electromagnet, and the restoring force of elastic component 31 makes baffle plate 20 in closing first
The primary importance of through hole 121, is controlled with stopping that the steam produced in cooking cavity 11 and high-temperature gas are entered via first through hole 121
In chamber 12.
In addition, when unexpected power-off is run into, 32 dead electricity of electromagnet, the restoring force of elastic component 31 make baffle plate 20 in closing the
The primary importance of one through hole 121, it is also possible to avoid steam in cooking cavity 11 from entering in control chamber 12 with high-temperature gas.
According to an example of the present invention, with vertically extending draw-in groove on baffle plate 20, the side wall of control chamber 12
Upper have the snap fit being adapted for limiting the movement locus of baffle plate 20 in the vertical direction with the draw-in groove.Advantageously, institute
Stating draw-in groove includes the lower bayonet slot 203 of the upper draw-in groove 202 of the upper end adjacent to baffle plate 20 and the lower end of neighbouring baffle plate 20.The snap fit
The lower snap fit 123 being adapted including the upper clamping hook 122 that is adapted with upper draw-in groove 202 and with lower bayonet slot 203.Thus, it is easy to gear
The installation of plate 20, and can ensure that baffle plate 20 accurately opens and closes first through hole 121.
According to a specific embodiment of the present invention, there is on baffle plate 20 second through hole 204.When baffle plate 204 is in described
During primary importance, first through hole 121 is offset one from another with the second through hole 204, so that part without perforate closes the on baffle plate 20
One through hole 121.When baffle plate 20 is in the second place, first through hole 121 is overlapped each other with the second through hole 204.First leads to
Hole 121 can be mutually the same or different from each other with the second through hole 204.First through hole 121 can include multiple, the second through hole 204
Including multiple correspondingly with multiple first through holes 121.
Micro-wave oven according to embodiments of the present invention, by changeover module make baffle plate close first through hole primary importance with
And open changeable between the second place of first through hole, first through hole can be opened and closed as needed, and then prevent water
Vapour enters control chamber with high-temperature gas, solves the problems, such as that the display screen of aobvious control plate produces water smoke, improves display quality, intercept
Steam is affected on controller, improves service life.At the same time it can also reduce heat losses so that cooking speed quickening, subtracts
Lack power consumption, reduce use cost.
