Abstract

The present application discloses a firepower regulating valve, a stove and a smoke and stove linkage device. When a user needs to adjust the firepower, the valve body is rotated to rotate the arc-shaped portion and the gear protrusion. The arc-shaped portion first touches the default gear switch to close the default gear switch. The default gear switch sends a corresponding trigger signal to turn on the stove according to the default firepower gear. When the user needs to switch to other firepower gears, he only needs to continue to rotate. The arc-shaped portion always keeps the state of touching the default gear switch, so that the gear protrusion on the outer peripheral wall of the arc-shaped portion touches any other micro switch to achieve the switching of the firepower gear, so that the firepower size of the stove can be easily identified. The micro switch is used to identify and control the switching of the firepower gear. Since the micro switch has a simpler opening and closing operation and less wear mechanism than the potentiometer, it has higher durability and reliability in the kitchen.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] The present application discloses a fire power regulating valve, a stove and a smoke and stove linkage device. The fire power regulating valve can be applied to any suitable stove, such as an integrated stove, a gas stove or an electric stove, etc.

[0043] The following is combined with Figures 1 to 9 , some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0044] The embodiment of the present application discloses a smoke and stove linkage device, which includes a stove and a range hood, and the type of the stove is not specifically limited, for example, it can be an integrated stove, a gas stove or an electric stove, etc. The air volume of the range hood can be adjusted according to the fire power of the stove to achieve wind and fire linkage between the stove and the range hood.

[0045] The stove includes a fire power regulating valve, a control panel and a stove head. The control panel is connected to the fire power regulating valve and the stove head in communication. By operating the fire power regulating valve to open, a corresponding gear signal can be output to the control panel. The control panel can judge the size of the fire power that the stove head needs to output according to the gear start signal, so as to control the stove head to output the fire power of the corresponding gear. In addition, the control panel can also send an air volume gear signal to the range hood after judging the corresponding fire power size, and the range hood can run the air volume of the corresponding gear according to the air volume gear signal, thereby realizing the linkage control of the range hood and the stove.

[0046] Combination Figures 1 to 3 The fire control valve includes a valve body 10, a valve stem 20 and M micro switches 30. The valve stem 20 is rotatably arranged on the valve body 10; the structure of the valve body 10 is basically the same as the existing structure, and this application will not elaborate on it. Usually, the valve stem 20 can also move axially relative to the valve body 10 to achieve locking or unlocking between the rear end of the valve stem 20 and the valve body 10, so that the user can apply force from the front end of the valve stem 20 to unlock the valve stem 20, and then rotate it to adjust the fire size of the stove.

[0047] The front end of the valve stem 20 is an end facing the outside of the stove and close to the user, and the rear end of the valve stem 20 is an end facing the inside of the stove and away from the user.

[0048] M micro switches 30 are disposed on the valve body 10 and distributed around the valve stem 20. Among all the micro switches 30, there are N default position switches 31, where M is a positive integer greater than or equal to 2, and N is a positive integer greater than or equal to 1 and less than M.

[0049] Among them, the outer peripheral wall of the valve stem 20 is provided with an arc portion 41 and a gear protrusion 42 arranged on the outer peripheral wall of the arc portion 41. The outer peripheral wall of the arc portion 41 is used to touch the default gear switch 31, and the gear protrusion 42 is used to touch any one of the M micro switches 30 except the default gear switch 31.

[0050] In this way, when the user needs to adjust the firepower, the arc portion 41 and the gear protrusion 42 rotate accordingly by rotating the valve body 10. The arc portion 41 first touches the default gear switch 31 to close the default gear switch 31. The default gear switch 31 sends a corresponding trigger signal to turn on the cooker according to the default firepower gear. When the user needs to switch to other firepower gears, he only needs to continue to rotate. The arc portion 41 always keeps the state of touching the default gear switch 31, so that the gear protrusion 42 on the outer wall of the arc portion 41 touches any other micro switch 30 to achieve the switching of the firepower gear, so that the firepower size of the cooker can be easily identified. The micro switch 30 is used to identify and control the switching of the firepower gear. Since the micro switch 30 has a simpler opening and closing operation and less wear mechanism than the potentiometer, it has higher durability and reliability in the kitchen.

[0051] It should be noted that when the cooker needs to be turned off, it is only necessary to rotate the valve stem 20 so that the arc portion 41 and the gear protrusion 42 move to a closed position that does not touch any micro switch 30. At this time, the gear protrusion 42 is misaligned with the contact of any micro switch 30, and the two ends of the arc portion 41 are opened to form a closed area 43, which corresponds to the default gear switch 31. The air volume gear of the range hood has a default air volume gear corresponding to the default gear switch 31, and one or more air volume gears corresponding to the number of micro switches 30 in the M micro switches 30 except the default gear switch 31.

[0052] Exemplary, combined Figure 4 and Figure 5 The total number of micro switches 30 can be set to three, so that the three micro switches 30 correspond to the low fire gear, the medium fire gear and the high fire gear respectively, and the corresponding air volume gear of the range hood is three, that is, the trigger signals of the range hood corresponding to the three micro switches 30 include the low wind gear, the medium wind gear and the high wind gear, and the number of the default gear switch 31 is one, which can be the corresponding identification of the medium fire gear, and the default air volume gear of the corresponding range hood is the medium wind gear. Of course, the default gear switch 31 can also be the corresponding identification of the low fire gear or the high fire gear, and the default air volume gear of the corresponding range hood is the low wind gear or the high wind gear. The specific firepower gear corresponding to the default gear switch 31 can be selected according to the default firepower size when the stove is turned on.

[0053] The other two micro switches 30 are respectively a low-fire gear switch 32 and a high-fire gear switch 33. When the arc portion 41 touches the default gear switch 31, the default gear switch 31 is closed. After the stove head of the stove is running at the medium-fire gear, if the valve stem 20 is continued to be rotated so that the gear protrusion 42 selectively touches the low-fire gear switch 32 or the high-fire gear switch 33, the switching between the low-fire gear and the high-fire gear is realized, and the corresponding range hood is also switched to the low-wind gear or the high-wind gear.

[0054] For example Figure 6 At this time, the default gear switch 31 is still closed, the gear protrusion 42 touches the low-fire gear switch 32, the low-fire gear switch 32 is closed, the stove head of the stove is at the low-fire gear, and the range hood is at the low-wind gear accordingly.

[0055] Another example Figure 7 At this time, the default gear switch 31 is still closed. When the gear protrusion 42 touches the high-fire gear switch 33, the high-fire gear switch 33 is closed, the stove head of the stove is in the high-fire gear, and the range hood is correspondingly in the high-wind gear.

[0056] Of course, it is understandable that the number of micro switches 30 can also be two, four or more than five, and the specific number is not limited and can be flexibly selected according to the number of fire power levels required for the stove.

[0057] Optionally, the default gear switch 31 is a lever-type microswitch 30, and the other microswitches 30 are button-type microswitches 30. In this way, when the arc portion 41 touches the lever of the lever-type microswitch 30 as the valve stem 20 rotates, the arc portion 41 and the lever can slide more smoothly to improve the touch reliability, while the other button-type switches are push-button switches, which is conducive to the precise touching of the gear protrusion 42.

[0058] In order to realize the installation of the micro switch 30 on the valve body 10, the valve body 10 includes a valve plate 11 and a valve cover 12. The micro switch 30 and the valve cover 12 are both installed on the valve plate 11, and the micro switch 30 is located in the space between the valve cover 12 and the valve plate 11. The valve stem 20 can be rotatably penetrated through the valve cover 12 and the valve plate 11.

[0059] Optionally, the arc portion 41 and the valve stem 20 may be arranged in a split manner, for example Figure 8 and Fig. 9 As shown, an annular rotating disk 40 is mounted on the valve stem 20 . The rotating disk 40 and the valve stem 20 can rotate synchronously, and an arc portion 41 is formed on the outer peripheral side of the rotating disk 40 .

[0060] Among them, since the valve stem 20 needs to move axially, in order to ensure that the arc portion 41 on the turntable 40 can touch the default gear switch 31 and the gear protrusion 42 can touch other micro switches 30, it is necessary to keep the position of the turntable 40 fixed relative to the micro switch 30, that is, the turntable 40 needs to be kept on the valve plate 11, so when the valve stem 20 moves axially, the valve stem 20 and the turntable 40 can slide relative to each other, and at the same time, it is also necessary to ensure that the turntable 40 can rotate with the valve stem 20 when it rotates, so the valve stem 20 and the turntable 40 can achieve anti-rotation cooperation through the flat position.

[0061] The surface of the gear protrusion 42 is specifically an arc surface, and along the radial direction from the center of the valve stem 20 toward the outside, the size of the gear protrusion 42 in the circumferential direction gradually decreases, so that the sliding contact between the gear protrusion 42 and the button contact of the micro switch 30 is smoother.

[0062] Continue to refer Figure 2 and Figure 3 Of course, in order to ensure that the turntable 40 can be maintained on the valve plate 11, an elastic member 50 can be provided between the valve cover 12 and the turntable 40. The elastic member 50 can be a coil spring which is mounted outside the valve stem 20. The elastic member 50 is used to keep the turntable 40 against the valve plate 11 at all times.

[0063] Specifically, a pressure plate 60 is mounted on the outer side of the valve stem 20, and the pressure plate 60 is located between the turntable 40 and the valve cover 12. The elastic member 50 abuts between the pressure plate 60 and the turntable 40, so that the elastic member 50 can push and apply force to the turntable 40 to fix the position of the turntable 40 relative to the micro switch 30, and at the same time will not affect the rotation of the turntable 40 with the valve stem 20 and the axial sliding of the valve stem 20 relative to the turntable 40.

[0064] In order to achieve axial limitation of the pressure plate 60 on the valve stem 20 and prevent the pressure plate 60 from moving away from the valve plate 11 under the action of the elastic member 50, a retaining spring 70 is fixed to the outer peripheral wall of the valve stem 20. The retaining spring 70 is located on the side of the pressure plate 60 facing away from the turntable 40, and the pressure plate 60 is abutted against the retaining spring 70 under the action of the elastic member 50.

[0065] A mounting groove 21 arranged around the central axis of the valve stem 20 may be provided on the outer peripheral wall of the valve stem 20 , and the retaining spring 70 is installed in the mounting groove 21 .

[0066] In order to ensure that the valve stem 20 can move axially normally, the pressure plate 60 and the valve stem 20 are anti-rotationally matched through a flat position, so that the pressure plate 60, the spring and the rotating disk 40 all rotate together with the valve stem 20.

[0067] Of course, in some embodiments, the pressure plate 60 and the retaining spring 70 may not be provided, and it is also feasible to directly place the elastic member 50 against between the valve plate 11 and the rotating disk 40 .

[0068] In addition, the arc portion 41 can also be integrally formed on the outer peripheral wall of the valve stem 20, as long as the axial dimensions of the arc portion 41 and the gear protrusion 42 in the valve stem 20 are sufficient to ensure that the arc portion 41 can still trigger the micro switch 30 to close when the valve stem 20 moves axially.

[0069] In summary, the embodiment of the present application discloses a firepower regulating valve, a stove and a smoke and stove linkage device. When the user needs to adjust the firepower, the valve body 10 is rotated to rotate the arc portion 41 and the gear protrusion 42 accordingly. The arc portion 41 first touches the default gear switch 31 to close the default gear switch 31. The default gear switch 31 sends a corresponding trigger signal to turn on the stove according to the default firepower gear. When the user needs to switch to other firepower gears, he only needs to continue to rotate. The arc portion 41 always keeps the state of touching the default gear switch 31, so that the gear protrusion 42 on the outer peripheral wall of the arc portion 41 touches any other micro switch 30 to achieve the switching of the firepower gear, so that the firepower size of the stove can be easily identified. The micro switch 30 is used to identify and control the switching of the firepower gear. Since the micro switch 30 has a simpler opening and closing operation and less wear mechanism than the potentiometer, it has higher durability and reliability in the kitchen.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it.
