Specific embodiment

The technical solution of the utility model is illustrated with embodiment with reference to the accompanying drawing.

As shown in figures 2 or 4, a kind of sealed valve with folding function described in the utility model, for oven In 1 exhaust passage of liner, gas vent 2 is offered on the liner 1, smoke exhaust pipe 3, the sealing are connected on the gas vent 2 Valve includes sealing plate 4 and actuator 5, and the sealing plate 4 has staggered positions and lap position with the gas vent 2, described Actuator 5 is for driving the sealing plate 4 mobile relative to gas vent 2, so that the sealing plate 4 is in above-mentioned staggered positions and again It is moved back and forth between folded position, thus gas vent 2 described in opening and closing of fault.The sealed valve of the utility model, is mounted on oven The position that liner 1 is in contact with discharge flue is specifically mounted on the gas vent 2 of 1 outer surface of liner, and sealed valve includes using In the sealing plate 4 for closing or opening gas vent 2, and the actuator 5 for driving sealing plate 4 to move back and forth, such sealing plate 4 Gas vent 2 automatically can be closed or be opened, open state is switched to when needing to discharge fume, is made under the driving of actuator 5 Liner 1 is connected with discharge flue, and the flue gas in liner 1 is discharged, closed state can be switched to when needing to close, will be interior Gallbladder 1 is kept apart with discharge flue, and the filter or strainer in discharge flue are also just isolated in outside liner 1, will not be to liner 1 In food cause secondary pollution.

The first embodiment of the utility model offers multiple Circle-Arrays on the liner 1 as shown in Figure 1, Figure 2 and Figure 3 Arrange the gas vent 2 of arrangement, the sealing leaf with the arrangement of multiple circumference array on the sealing plate 4；The actuator 5 includes driving Bar 6 and driver 7, the drive rod 6 are rotatably installed on liner 1, the sealing plate 4 be fixed on drive rod 6 and with The gas vent 2 fits；The driver 7 is for driving the drive rod 6 to rotate, so that the sealing plate 4 is relative to row Stomata 2 rotates, so that the sealing plate 4 be made to move back and forth between above-mentioned staggered positions and lap position.By with circumference The sealing plate 4 of multiple sealing leaves of arrangement cooperates with the gas vent 2 of multiple circumference arrangement, in the on state can the row of being promoted Gas efficiency, when needing to close, sealing plate 4, which only needs to rotate an angle, can complete closing movement, such sealed valve Structure is more simple and reliable, and sealing effect is more preferable.

As shown in Figure 1, one end of the drive rod 6 is rotatably installed on liner 1, the other end is rotatably installed on On smoke exhaust pipe 3；The position that the drive rod 6 is in contact with smoke exhaust pipe 3 is equipped with sealing ring 8.The both ends of drive rod 6, which are all made of, to be turned Dynamic structure is installed, at the same on drive rod 6 be arranged sealing ring 8, keep the rotational structure of drive rod 6 more stable, and with row Better tightness between smoke pipe 3, prevents flue gas from leaking.

As shown in Figure 1 or 2, elastic component 9 is equipped between the drive rod 6 and sealing plate 4, the elastic component 9 is used for will The sealing plate 4 is pressed on gas vent 2.The elastic force applied by elastic component 9 to sealing plate 4, allows sealing plate 4 closely It is fitted on gas vent 2, it in this way can be so that leakproofness of the sealing plate 4 in closed grate hole 2 be higher.

As shown in Figure 1, being sequentially connected between the driver 7 and drive rod 6 by connector sleeve 10.It will by connector sleeve 10 Driver 7 and the transmission connection of drive rod 6 are got up, and can guarantee reliable transmission between the two, while also simplifying drive mechanism.

The second embodiment of the utility model, as shown in figure 4, offering multiple exhausts linearly arranged on the liner 1 Hole 2 has multiple sealing leaves linearly arranged on the sealing plate 4；The actuator 5 is linear for driving the sealing plate 4 It is mobile, so that the sealing plate 4 be made to move back and forth between above-mentioned staggered positions and lap position.By with linearly aligned The sealing plate 4 of multiple sealing leaves, matches with multiple linearly aligned gas vents 2, can promote exhaust effect in the on state Rate, when needing to close, sealing plate 4 only needs a mobile lesser spacing that can complete closing movement, such sealed valve Structure it is more simple and reliable, sealing effect is more preferable.Above-mentioned linearly can choose laterally or vertically arranges, such sealing plate 4 It can horizontally slip perhaps to slide up and down and can realize closing or unlatching gas vent 2.

As shown in Figure 1, the actuator 5 is equipped with block 11, it is equipped with touch switch 12 with 11 corresponding position of block, The touch switch 12 is connected on actuator 5 to commutate for controlling the actuator 5.Pass through 11 He of block on actuator 5 Touch switch 12 cooperates, and enables 5 automatic reverse of actuator, and the moving direction when driving sealing plate 4 is more acurrate, guarantees sealing plate 4 state switching does not malfunction.

Oven with sealed valve provided by the utility model when in use, can cook demand according to user to select Opening and closing of fault gas vent 2, user can realize the manipulation of actuator 5 by corresponding control panel, mention actuator 5 For power, sealing plate 4 is driven to complete scheduled movement.Specifically, as shown in Figure 1, driver 7 uses motor, in its operating Drive rod 6 is driven to rotate by the transmission of connector sleeve 10, such sealing plate 4 is just rotated synchronously with drive rod 6, when needing to discharge fume, Sealing leaf and gas vent 2 on sealing plate 4 can relatively rotate staggered positions, and gas vent 2 is turned on, in such liner 1 Flue gas can be entered in discharge flue by gas vent 2, be discharged under fan action in discharge flue, while can also To filter out the harmful substance in flue gas through the devices such as filter screen or filter, make noxious substance in strainer or filter It is interior, prevent harmful substance to be directly discharged to cause environmental pollution in external environment；When not needing smoke evacuation, actuator 5 can be anti- To operating, drive rod 6 is driven to rotate backward with sealing plate 4 by connector sleeve 10, the sealing leaf on sealing plate 4 and gas vent 2 It can relatively rotate to lap position, gas vent 2 is sealed, and liner 1 is isolated with discharge flue, in discharge flue Deleterious characteristics in impurity and strainer or filter are also isolated in discharge flue, not can enter liner 1, can thus be kept away Exempt from harmful substance and secondary pollution is caused to the food in liner 1.In addition, as shown in figure 4, actuator 5 can also using manually or Motor-driven mode, artificial or motor driven sealing plate 4, no matter which kind of driving method, actuator 5 all can be with sealing plate 4 Linear to move back and forth, when needing to discharge fume, sealing plate 4 can be moved to sealing leaf thereon and be in staggered positions with gas vent 2, Gas vent 2 is turned on；On the contrary, sealing plate 4 can be reversed sealing leaf and the gas vent being moved to thereon when not needing smoke evacuation 2 are in lap position.Further, pass through the cooperation of block 11 and touch switch 12 on actuator 5, moreover it is possible to realize intelligent Automation control, by the cooking process on oven, oven can automatically select whether need to discharge fume, accordingly control driving The movement of part 5, to realize that sealing plate 4 switches in two location status, to realize the opening and closing of fault of gas vent 2.

The above description is only a preferred embodiment of the present invention, therefore all according to described in the utility model patent application range The equivalent change or modification done of structure, feature and principle, be included in the scope of the utility model patent application.
