[0001] The present application belongs to the technical field of kitchen heating equipment, and particularly relates to a control device and a gas stove. BACKGROUND

[0002] The gas stove refers to a kitchen appliance that directly heats by using gaseous fuel such as liquefied petroleum gas (liquid state), artificial gas, and natural gas. With the improvement of user demand, some gas stoves have already had intelligent control functions.

[0003] In the related art, the gas stove with the intelligent control function realizes the human-computer interaction of the user by using a touchable display screen. The power consumption of the touchable display screen is large, and therefore the gas stove needs to be connected to the mains to have a good user experience, which leads to a more complex arrangement of the gas stove. SUMMARY

[0009] At least two function circuits have corresponding contacts on the fixed part, and the movable part can move relative to the fixed part to make the activation part act on the contacts of any function circuit to make the function circuit turn on.

[0010] In the control device of the embodiments of the present application, the fixed part and the movable part are arranged on the panel of the gas stove, the movable part can move relative to the fixed part, and the activation part connected to the movable part can move with the movable part. In this way, the activation part can act on the contacts of any function circuit on the fixed part to control the gas stove to realize different functions, thereby achieving the purpose of simplifying the control mode of the gas stove. The fixed part and the movable part are arranged on the side of the panel away from the inside of the gas stove, so that the fixed part and the movable part do not have to be installed in the inside of the gas stove, which makes the installation of the fixed part and the movable part convenient and facilitates the cleaning of the fixed part and the movable part.

[0011] In some embodiments, the movable part is rotatably sleeved on the fixed part, the activation part is arranged on the inner wall of the movable part, and the contacts of the function circuit are located on the outer wall of the fixed part.

[0012] By fitting the movable part onto the fixed part, the movable part can rotate relative to the fixed part to move the activated part, thereby reducing the range of movement of the movable part and making the control device structure more compact.

[0013] In some embodiments, the control device further includes a resistor plate disposed around the side wall of the fixed part, the contacts of the functional circuit being located on the resistor plate, and one end of the activating part being rotatable with the movable part to be electrically connected to any contact on the resistor plate.

[0014] By making the activating part contact different positions with the resistive sheet, the path formed by the first electrical connection and the resistive sheet can have different resistance values, thereby connecting different functional circuits.

[0015] In some embodiments, the control device further includes a protrusion, the gas stove panel has a positioning hole, the protrusion is connected to the fixing part, the protrusion extends into the positioning hole and is connected to the inner wall of the positioning hole.

[0017] In some embodiments, the fixing part is sleeved on the valve stem of the gas stove, the positioning hole penetrates the panel of the gas stove, and the valve stem of the gas stove passes through the positioning hole.

[0018] By fitting the fixing part onto the valve stem, the structure of the control device can be made more compact.

[0019] In some embodiments, there is a gap between the movable part and the fixed part, and there is also a gap between the fixed part and the valve stem of the gas stove.

[0020] The gap between the fixed part and the moving part ensures that the valve stem does not interfere with the moving part and the fixed part when it rotates.

[0021] In some embodiments, the gas stove further includes a flame adjustment knob, which is connected to the end of the gas stove's valve stem extending to the side of the gas stove's panel facing away from the interior of the gas stove, and has a gap with the fixing part.

[0022] The fire control knob facilitates valve stem rotation, and the gap between the fire control knob and the fixed part prevents them from interfering with each other.

[0024] By setting a first baffle and a second baffle, foreign objects can be prevented from falling into the gas stove through the gap between the valve stem and the positioning hole.

[0025] In some embodiments, the control device further includes an elastic element, the movable part having a plurality of positioning grooves distributed along the moving direction of the movable part, one end of the elastic element being connected to the fixed part, and the other end of the elastic element being able to be embedded in the positioning groove.

[0026] By setting an elastic element that cooperates with the positioning groove, the position of the movable part can be fixed more easily, so that the position adjustment of the movable part is accurate.

[0027] In some embodiments, the inner wall of the positioning groove is an arc surface, and the shape of one end of the elastic element embedded in the positioning groove matches the groove shape of the positioning groove.

[0028] By setting the inner wall of the positioning groove to an arc surface, one end of the elastic element can be disengaged from the positioning groove by rotating the movable part.

[0047] This application is described below with reference to the accompanying drawings and specific embodiments:

[0048] Example 1

[0049] Please refer to Figures 1-9 This application discloses a control device including a fixed part 200, a movable part 300, an activation part 310, and at least two functional circuits. This control device can be applied to a gas stove to control the gas stove to perform various functions.

[0050] It should be understood that the gas stove has a panel 100, which is the upper side panel of the gas stove. One side of the panel 100 faces the inside of the gas stove, and the other side of the panel 100 faces away from the inside of the gas stove. When using the gas stove, the user can directly observe the various components on the panel 100. Specifically, the gas stove's switches and knobs are all located on the side of the panel 100 facing away from the inside of the gas stove.

[0051] In this application, the fixed part 200 is disposed on the panel 100 of the gas stove and is located on the side of the panel 100 facing away from the interior of the gas stove. The movable part 300 is movably disposed on the side of the panel 100 facing away from the interior of the gas stove, so that the movable part 300 can be moved and the relative positional relationship between the movable part 300 and the fixed part 200 can be changed.

[0052] At least two functional circuits can be electrically connected to components of the gas stove, and different functions can be achieved by activating different functional circuits. Specifically, functional circuits can be set for controlling the gas stove to shut off at a set time, for controlling the timed change of the gas stove's flame intensity, and for controlling the position of the gas stove's flame, etc. This application does not limit the specific functions of the functional circuits.

[0053] Two functional circuits form corresponding contacts on the fixed part 200, with the number of contacts corresponding to the number of functional circuits. An activation part 310 is disposed on the movable part 300. Therefore, as the movable part 300 moves relative to the fixed part 200, the activation part 310 also moves with the movable part 300. During this movement, the activation part 310 acts on the contacts of any one of the at least two functional circuits, thereby activating that functional circuit and enabling the gas stove to perform the function corresponding to that circuit. The movement of the movable part 300 can cause the activation part 310 to act on the contacts of different functional circuits, activating different functional circuits.

[0054] It should be understood that the control device of this application may be provided with a circuit board. Specifically, at least two functional circuits may be provided on the circuit board, which may be provided inside the gas stove. The circuit board may be provided with wires corresponding to multiple functional circuits, and one end of the wire may pass through the panel 100 and extend to the fixing part 200 to form a contact.

[0055] During the adjustment of the movable part 300 relative to the fixed part 200, since both the movable part 300 and the fixed part 200 are located on the side of the gas stove panel 100 facing away from the inside of the gas stove, the fixed part 200 and the movable part 300 can be easily installed on the gas stove panel 100 without having to be located inside the gas stove. This makes the process of installing and removing the fixed part 200 and the movable part 300 simple and convenient.

[0056] In the control device of this embodiment, the fixed part 200 and the movable part 300 are disposed on the panel 100 of the gas stove. The movable part 300 is movable relative to the fixed part 200, so that the activation part 310 connected to the movable part 300 can move with the movable part 300. In this way, the activation part 310 can act on the contact of any functional circuit on the fixed part 200, thereby activating the functional circuit to control the gas stove to achieve different functions, thus simplifying the control method of the gas stove. Both the fixed part 200 and the movable part 300 are disposed on the side of the panel 100 facing away from the inside of the gas stove. In this way, the fixed part 200 and the movable part 300 do not need to be installed inside the gas stove, making the installation of the fixed part 200 and the movable part 300 convenient, and also making it easy to clean the fixed part 200 and the movable part 300.

[0057] In some embodiments, to make the structure of the movable part 300 and the fixed part 200 compact when disposed on the panel 100 of the gas stove, the movable part 300 may be configured to be sleeved on the fixed part 200, and the movable part 300 may be rotatable around the fixed part 200. Contacts formed by at least two functional circuits on the fixed part 200 may be disposed at different locations on the outer peripheral wall of the fixed part 200 facing the movable part 300. Correspondingly, the activation part 310 may be disposed on the inner wall of the movable part 300 facing the fixed part 200. During the rotation of the movable part 300 relative to the fixed part 200, the activation part 310 may rotate with the movable part 300, so that the activation part 310 can act on the contacts of different functional circuits on the outer peripheral wall of the fixed part 200, thereby activating the different functional circuits.

[0058] Specifically, the activation part 310 is disposed after the movable part 300. The side of the activation part 310 facing away from the movable part 300 can be configured to contact the outer peripheral wall of the fixed part 200. During the movement of the movable part 300, one end of the activation part 310 can rotate along the outer peripheral part of the fixed part 200 until it rotates to contact the contact of any functional circuit, so that the functional circuit is activated.

[0059] By rotating the movable part 300 around the fixed part 200, the activation part 310 acts on the contacts of each functional circuit. In this way, during the change of position of the activation part 310, the movable part 300 will not move along the gas stove panel 100, and the relative positional relationship between the movable part 300 and the gas stove panel 100 will not change. This achieves the purpose of reducing the space occupied by the movable part 300 on the gas stove panel 100, thereby making the structure of the control device of this application more compact.

[0060] Of course, in other embodiments, the movable part 300 may also be configured to move relative to the panel 100 of the gas stove in a preset direction. The preset direction may be a straight line. Correspondingly, the movable part 300 may be disposed on one side of the fixed part 200, and the contacts of the functional circuits may be distributed in the fixed part 200 in a preset direction. The activation part 310 may move with the movable part 300 in a preset direction, so that one end of the activation part 310 may act on the contacts of each functional circuit distributed in the preset direction during the process of moving in the preset reverse direction.

[0061] Specifically, in this embodiment, the contacts of the functional circuits can be disposed on the outer wall of the fixed part 200 facing the movable part 300. One end of the activation part 310 can be configured to connect with the outer wall of the movable part 300 facing the fixed part 200, and the other end of the activation part 310 can be configured to contact the outer wall of the fixed part 200 facing the movable part 300. In this way, the activation part 310 can move in a preset direction to make the activation part 310 contact the contacts of each functional circuit, thereby activating the activation part 310 with the functional circuit.

[0062] By configuring the movable part 300 as described above, it can move relative to the gas stove panel 100, making changes in the positional relationship between the movable part 300 and the fixed part 200 clearly observable. This makes operating the movable part 300 more intuitive for the user. Especially in low-light environments, users can adjust the positional relationship between the movable part 300 and the fixed part 200 by blind operation to select different functions.

[0063] In some embodiments, in order to enable the various functional circuits to form contacts on the fixed part 200, the control device of this application may also be provided with a resistor 210. The resistor 210 may be disposed around the outer peripheral wall of the fixed part 200, and the contacts of the functional circuits are located on the resistor 210. The activation part 310 may be an electrical connector. The end of the activation part 310 away from the movable part 300 may be configured to contact the resistor 210. During the movement of the activation part 310 with the movable part 300, the end of the activation part 310 away from the movable part 300 may contact various parts of the resistor 210 so that different functional circuits are activated.

[0064] Specifically, during the rotation of the activation part 310 along the resistor sheet 210, the activation part 310 contacts different parts of the resistor sheet 210, which can make the parts of the resistor sheet 210 that contact the activation part 310 have different resistance values. The control device of this application can be equipped with a function selection circuit that is electrically connected to multiple functional circuits and the resistor sheet 210. The function selection circuit can determine the resistance value after the activation part 310 contacts the resistor sheet 210, and activate different functional circuits according to different resistance values ​​so that the gas stove can achieve different functions.

[0065] In other embodiments, the control device of this application may also include a Hall sensor and a function selection circuit. The activation unit 310 may be a magnetic component. The function selection circuit is electrically connected to the Hall sensor and multiple function circuits. The Hall sensor may be mounted on the fixed part 200, specifically integrated inside the fixed part 200. As the magnetic component moves with the movable part 300, the magnetic field formed by the magnetic component changes accordingly. This allows the Hall sensor to detect different magnetic field signals, and the function selection circuit can activate different function circuits based on the different magnetic field signals, thus achieving the purpose of controlling various functions of the gas stove.

[0066] Therefore, the contacts of the functional circuit can be understood as the magnetic components being in different positions. When the magnetic components are in different positions, the magnetic field signals detected by the Hall sensor can correspond to different functional circuits, so as to realize the activation selection of the functional circuit.

[0067] In some embodiments, the contacts of the functional circuit of this application may also be configured as microswitches, and the activation part 310 may be configured as an electrical connector, specifically, a metal sheet. By moving the movable part 300, the activation part 310 may be made to contact the microswitches of different functional circuits, so as to open the microswitches and activate the functional circuits.

[0068] Alternatively, the contacts of the functional circuit can be configured as microswitches that can be pressed open, and the activation part 310 can be configured as an insulating part. By moving the movable part 300, the activation part 310 can act on the microswitch, specifically by pressing the microswitch, so that the microswitch is opened and the functional circuit corresponding to the microswitch is activated.

[0069] This application does not impose any restrictions on the specific structure of the activation unit 310 and the contacts of the functional circuit.

[0070] Furthermore, it should be noted that a connector 260 may be provided on the fixing part 200. The connector 260 can be connected to the circuit board inside the gas stove via wires, or an interface can be provided on the circuit board for direct connection to the connector 260 on the fixing part 200. When a micro switch is provided on the fixing part 200, the connector 260 can communicate with the micro switch or with other electrical connectors on the fixing part 200, so that the functional circuit can form contacts on the fixing part 200.

[0071] In some embodiments, to facilitate rotation of the movable part 300 relative to the fixed part 200, the movable part 300 may also include a grip ring 330, which is sleeved on the movable part 300. The circumferential outer wall of the grip ring 330 may have multiple grooves to increase friction when the user rotates the grip ring 330, thereby facilitating rotation of the grip ring 330 and the movable part 300 connected to it. Alternatively, protrusions may be provided on the circumferential outer wall of the grip ring 330 to facilitate user rotation.

[0072] In some embodiments, to make the fixing part 200 more stable and reliable when it is fixedly installed on the panel 100 of the gas stove, the control device of this application may also be provided with a protrusion 220. A positioning hole 110 may be opened on the panel 100 of the gas stove, and the protrusion 220 may be embedded in the positioning hole 110. The outer wall of the protrusion 220 fits against the inner wall of the positioning hole 110, so that the positioning hole 110 can limit the protrusion 220, thereby fixing and limiting the fixing part 200 to prevent the fixing part 200 from moving relative to the panel 100 of the gas stove.

[0073] Of course, in order to further ensure that the fixing part 200 is reliably fixed to the panel 100, the fixing part 200 can be fixed to the panel 100 of the gas stove by adhesive bonding. Correspondingly, the protrusion 220 can also be fixed to the positioning hole 110 by adhesive bonding. In this way, the fixing part 200, the protrusion 220 and the panel 100 of the gas stove do not need to have separate fixing connection structures, thereby simplifying the structure of the control device of this application.

[0074] In addition, the positioning hole 110 mentioned above can be set as a through hole that passes through the panel 100 of the gas stove, so that the positioning hole 110 can allow wires to pass through, thereby allowing the wires on the circuit board to extend through the positioning hole 110 to connect with the fixing part 200.

[0075] In some embodiments, in order to make the control device structure of this application more compact, the fixed part 200 of this application can be sleeved on the valve stem 400 of the gas stove, and correspondingly, the movable part 300 is also arranged around the valve stem 400 of the gas stove, so as to make full use of the structure of the valve stem 400 of the gas stove.

[0076] It should be understood that the valve stem 400 of the gas stove is a mechanism used to adjust the flame intensity of the gas stove. By rotating the valve stem 400, the flame intensity of the gas stove can be changed. One end of the valve stem 400 is located on the side of the gas stove panel 100 facing away from the inside of the gas stove, so that the user can operate and rotate the valve stem 400. The other end of the valve stem 400 extends into the inside of the gas stove and is connected to the flame intensity adjustment mechanism of the gas stove. Therefore, the valve stem 400 is set through the gas stove panel 100, and the gas stove panel 100 also has a through hole for the valve stem 400 to pass through.

[0077] The through hole on the panel 100 of the gas stove for the valve stem 400 to pass through can be used as the positioning hole 110. Therefore, the positioning hole 110 can allow the wires of the circuit board to pass through and the valve stem 400 of the gas stove to pass through. In this way, it is not necessary to separately open through holes on the panel 100 of the gas stove for the valve stem 400 and the wires to pass through.

[0078] The fixing part 200 can be sleeved on the valve stem 400 of the gas stove. Therefore, the fixing part 200 should be provided with a through hole for the valve stem 400 of the gas stove to pass through. Specifically, the through hole can be located in the center of the fixing part 200, specifically as a center hole 240. The inner diameter of the center hole 240 of the fixing part 200 can be set to be larger than the outer diameter of the valve stem 400 of the gas stove. This allows for a certain gap between the inner wall of the center hole 240 of the fixing part 200 and the outer wall of the valve stem 400 of the gas stove. When the valve stem 400 of the gas stove is rotated to adjust the flame of the gas stove, the fixing part 200 will not rotate with the valve stem 400 of the gas stove, and the fixing part 200 will not create resistance to the rotation of the valve stem 400 of the gas stove, thereby making the flame adjustment of the gas stove smoother.

[0079] By fitting the fixing part 200 onto the valve stem 400 of the gas stove, the fixing part 200 can make full use of the part on the panel 100 of the gas stove used for mounting the valve stem 400, and use the through hole on the panel 100 of the gas stove through which the valve stem 400 of the gas stove passes to form a positioning hole 110, so that the protrusion 220 of the fixing part 200 can be embedded in the through hole, and the wires of the circuit board can also pass through.

[0080] In some embodiments, the control device of this application is disposed on a gas stove. The gas stove may also be provided with a flame adjustment knob 410, which may be configured to be connected to the valve stem 400 of the gas stove. Specifically, the valve stem 400 of the gas stove has a first end located inside the gas stove and a second end extending to the side of the gas stove panel 100 facing away from the inside of the gas stove. The flame adjustment knob 410 may be connected to the end of the gas stove valve stem 400 extending to the side of the gas stove panel 100 facing away from the inside of the gas stove, that is, connected to the second end of the valve stem 400. In this way, the user can rotate the valve stem 400 of the gas stove by rotating the flame adjustment knob 410, thereby achieving the purpose of adjusting the flame of the gas stove.

[0081] Specifically, the second end of the valve stem 400 extends out of the fixed part 200 through the central hole 240. The flame adjustment knob 410 is a cap-shaped structure. The flame adjustment knob 410 can be configured to have a certain gap with both the fixed part 200 and the movable part 300. In this way, the flame adjustment knob 410 is in a non-contact state with both the fixed part 200 and the movable part 300. When the flame adjustment knob 410 is rotated, the movable part 300 will not be affected by the flame adjustment knob 410 and will not cause resistance to the rotation of the flame adjustment knob. Similarly, during the rotation of the movable part 300 relative to the fixed part 200, the movable part 300 will not drive the flame adjustment knob 410 to rotate, so that the flame adjustment and function selection of the gas stove using the control device of this application do not affect each other.

[0082] Furthermore, the area of ​​the end face of the flame adjustment knob 410 facing the fixing part 200 can be set to be no less than the cross-sectional area of ​​the central hole 240 of the fixing part 200. This allows the flame adjustment knob 410 to cover the center hole of the fixing part 200, effectively blocking the central hole 240 and preventing foreign objects from entering the gas stove through it. Additionally, the flame adjustment knob 410 and the valve stem 400 of the gas stove can be detachably connected. When cleaning the fixing part 200 is required, the fixing part 200 can be exposed by detaching the flame adjustment knob 410 from the valve stem 400, facilitating cleaning by the user.

[0083] In some embodiments, to further prevent foreign objects from entering the gas stove through the central hole 240 of the fixing part 200, the control device of this application may also be provided with a first baffle 230 and a second baffle 411. The second baffle 411 is disposed on the side of the flame adjustment knob 410 facing the fixing part 200, and the first baffle 230 is disposed on the side of the fixing part 200 facing the flame adjustment knob 410. Therefore, the first baffle 230 and the second baffle 411 are disposed opposite to each other. The second baffle 411 may also sleeve at least a portion of the first baffle 230 inside it. The outer wall of the first baffle 230, the inner wall of the second baffle 411, and the outer wall of the fixing part 200 all have a certain gap. In this way, when the flame adjustment knob 410 is rotated, the second baffle 411 will not rub against the first baffle 230 and the fixing part 200, so that the flame adjustment knob 410 rotates smoothly.

[0084] Since the first baffle 230 and the second baffle 411 are respectively disposed on the fixing part 200 and the fire power adjustment knob 410, the second baffle 411 sleeves the first baffle 230 inside, and there is a gap between the two. The opening of the gap faces the fixing part 200. Therefore, impurities and foreign objects on the side of the gas stove panel 100 facing away from the inside of the gas stove cannot enter the fixing part 200 through the gap between the first baffle 230 and the second baffle 411, so as to prevent foreign objects from entering the inside of the gas stove.

[0085] In some embodiments, it should be understood that when the movable part 300 moves relative to the fixed part 200, it can drive the activation part 310 to move with the movable part 300. The activation part 310 can act on the contacts of different functional circuits when it is in different positions. After the activation part 310 acts on the contacts of the functional circuit to make an electrical connection, the activation part 310 needs to remain stable so that the activation part 310 and the contacts of the functional circuit have a good electrical connection effect.

[0086] Therefore, the control device of this application is also provided with an elastic member 250. The inner wall of the movable part 300 facing the fixed part 200 can be provided with a plurality of positioning grooves 320 arranged circumferentially along the movable part 300. One end of the elastic member 250 is connected to the fixed part 200, and the other end of the elastic member 250 can be embedded in the positioning groove 320 of the movable part 300. Therefore, when the movable part 300 rotates relative to the fixed part 200, one end of the elastic member 250 can be respectively embedded in each positioning groove 320 of the movable part 300. After one end of the elastic member 250 is embedded in a positioning groove 320 of the movable part 300, the elastic member 250 can limit the movable part 300 to prevent the movable part 300 from continuing to rotate when there is no external force or the external force is small.

[0087] Specifically, the multiple positioning slots 320 of the movable part 300 are positioned to correspond to the contacts of various functional circuits. When one end of the elastic member 250 is embedded in a positioning slot 320, the activation part 310 acts on the contact of a functional circuit. If the user needs to switch the function of the gas stove, a larger force needs to be applied to the elastic member 250 to compress it. This increases the distance between one end of the elastic member 250 and the positioning slot 320 of the movable part 300, causing one end of the elastic member 250 to disengage from the positioning slot 320. When the movable part 300 rotates to a position where another positioning slot 320 is opposite one end of the elastic member 250, the restoring deformation force of the elastic member 250 allows one end of the elastic member 250 to be embedded in another positioning slot 320, and the activation part 310 can then act on the contact of another functional circuit.

[0088] Furthermore, the inner wall of the positioning groove 320 can be configured as an arc surface. Specifically, the groove shape of the positioning groove 320 is a spherical structure. One end of the elastic member 250, which is used to be embedded in the positioning groove 320, can be configured to mate with the groove shape of the positioning groove 320. Thus, when one end of the elastic member 250 is embedded in a positioning groove 320, by rotating the movable part 300, one end of the elastic member 250 can slide along the inner wall of the positioning groove 320, thereby allowing one end of the elastic member 250 to disengage from the positioning groove 320. Specifically, one end of the elastic member 250 can be provided with a spherical member 251.
