Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
Below with reference to the accompanying drawings the micro-wave oven according to the embodiment of the present invention is described in detail.
As shown in Figures 1 to 7, according to the micro-wave oven of the embodiment of the present invention, comprising: body of heater 10, baffle plate 20 and changeover module 30.
Specifically, there is cooking cavity 11 and control chamber 12 in body of heater 10.Wherein, the sidewall of control chamber 12 has the first through hole 121 being communicated with cooking cavity 11.Be understandable that, cooking cavity 11 is for cooking food, and control chamber 12 is for installing the electric component such as aobvious control plate, controller of micro-wave oven.In addition, " sidewall " here should be made narrow sense and understand, and refers in particular to that sidewall that cooking cavity 11 and control chamber 12 share.
Baffle plate 20 is located on the sidewall of control chamber 12 movably.Changeover module 30 to be located on body of heater 10 and to be connected with baffle plate 20.Changeover module 30 can make baffle plate 20 the primary importance (as shown in Figure 4 and Figure 5) of closedown first through hole 121 and open the first through hole 121 the second place (as shown in Figure 6 and Figure 7) between changeable.
According to the micro-wave oven of the embodiment of the present invention, by changeover module make baffle plate the primary importance of closedown first through hole and open the first through hole the second place between changeable, the first through hole can be opened and closed as required, and then prevent steam and high-temperature gas from entering control chamber to cause damage to the electric component in control chamber.
More specifically, according to an example of the present invention, the upper end of baffle plate 20 has the lead 201 being suitable for the roof being upward through control chamber 12.
Changeover module 30 comprises: elastic component 31, electromagnet 32 and screw 33.
The elastic component 31 of such as spring is socketed on lead 201.Elastic component 31 times (namely indicated under arrow as shown in Figure 4 direction) end is against upper (namely indicated on the arrow as shown in Figure 4 direction) end of baffle plate 20 and the upper end of elastic component 31 is in described primary importance against the roof of control chamber 12 with the described baffle plate of normal promotion downwards, and namely baffle plate 20 closes the position of the first through hole 121.
The roof that electromagnet 32 is fixedly installed on control chamber 12 is connected with the upper end of lead 201.Advantageously, electromagnet 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, the elastic force that electromagnet 32 overcomes elastic component 31 is in the described second place to make baffle plate 20, and namely baffle plate 20 opens the position of the first through hole 121.
As shown in Figure 4 and Figure 5, when electromagnet 32 is in power failure state, baffle plate 20 is in primary importance under the effect of the restoring force of elastic component 31.
Be understandable that, electromagnet 32 is suitable for being electrically connected with the controller of micro-wave oven.When microwave oven cooking food, controller can decide baffle plate 20 by the pressure reduction comparing cooking cavity 11 and control chamber 12 and open or cut out the first through hole 121.
That is, when microwave oven cooking food and radiator fan is opened time, the pressure now in cooking cavity 11 is less than the pressure in control chamber 12, and the steam produced in cooking cavity 11 and high-temperature gas can not enter in control chamber 12 via the first through hole 121.Now, baffle plate 20 both can be in primary importance, also can be in the described second place.
And when microwave oven cooking food and radiator fan close time, pressure now in cooking cavity 11 is greater than the pressure in control chamber 12, the controller of micro-wave oven can control electromagnet 32 dead electricity, the restoring force of elastic component 31 makes baffle plate 20 be in the primary importance of closedown first through hole 121, enters in control chamber 12 via the first through hole 121 with the steam and high-temperature gas that stop generation in cooking cavity 11.
In addition, when running into unexpected power-off, electromagnet 32 dead electricity, the restoring force of elastic component 31 makes baffle plate 20 be in the primary importance of closedown first through hole 121, and steam and high-temperature gas in cooking cavity 11 also can be avoided to enter in control chamber 12.
According to an example of the present invention, baffle plate 20 having the draw-in groove extended along the vertical direction, the sidewall of control chamber 12 having the suitable snap fit of movement locus for limiting baffle plate 20 in the vertical direction with described draw-in groove.Advantageously, described draw-in groove comprises the lower bayonet slot 203 of the upper draw-in groove 202 of the upper end of contiguous baffle plate 20 and the lower end of contiguous baffle plate 20.Described snap fit comprises the upper clamping hook 122 suitable with upper draw-in groove 202 and the lower bayonet slot 123 suitable with lower bayonet slot 203.Thus, be convenient to the installation of baffle plate 20, and can ensure that baffle plate 20 opens and closes the first through hole 121 accurately.
According to a specific embodiment of the present invention, baffle plate 20 has the second through hole 204.When baffle plate 204 is in described primary importance, the first through hole 121 and the second through hole 204 offset one from another, to make baffle plate 20 the not having part of perforate close the first through hole 121.When baffle plate 20 is in the described second place, the first through hole 121 and the second through hole 204 overlap each other.First through hole 121 can be mutually the same or different from each other with the second through hole 204.First through hole 121 can comprise multiple, and the second through hole 204 comprises with multiple first through hole 121 multiple one to one.
According to the micro-wave oven of the embodiment of the present invention, by changeover module make baffle plate the primary importance of closedown first through hole and open the first through hole the second place between changeable, the first through hole can be opened and closed as required, and then prevent steam and high-temperature gas from entering control chamber, the display screen solving aobvious control plate produces the problem of water smoke, improve display quality, having intercepted steam affects controller, improves service life.Meanwhile, heat losses can also be reduced and accelerate to make cooking speed, decrease power consumption, reduce use cost.
