Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils, and in particular to a stove. Background Technology

[0002] Most gas stoves on the market today use atmospheric burners. These burners work by having gas flow from a nozzle at a certain pressure and velocity into an injector tube. The gas then draws in primary air using its own energy. The gas and primary air mix in the injector tube and then flow out through the burner cap's flame holes for combustion, forming a flame. This is why most gas stoves have openings at the bottom of the casing—to provide an appropriate inlet for primary air.

[0003] Current designs typically include a single, fixed primary air inlet with an area that cannot be adjusted. While this design is relatively simple, it also presents several problems:

[0004] Question 1: The entrance area is either fully open or fully closed, meaning the opening is either completely open or completely sealed, making stepless adjustment impossible.

[0005] Question 2: If the opening is completely open, the gas stove may extinguish the flame when the cabinet door is opened or closed when the flame is low.

[0006] Question 3: If the opening is completely sealed, when the gas stove is turned on high, it is easy to cause insufficient air supply, which can lead to incomplete combustion and low combustion efficiency. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the defect of the existing technology where the single input is not adjustable, and to provide a stove.

[0008] The present invention solves the above-mentioned technical problems through the following technical solution:

[0009] A cooker includes: a bottom shell, a knob, an angle sensor, a drive mechanism, and a baffle.

[0010] An air inlet is provided on the bottom shell, which is opened and closed by a baffle. The drive mechanism is used to drive the opening and closing of the baffle. The angle sensor is used to detect the rotation angle of the knob and is electrically connected to the drive mechanism.

[0011] In this design, the angle sensor and drive mechanism in the stove are electrically connected, so that the opening of the baffle can be controlled by detecting the rotation angle of the knob. When the knob controls the firepower to increase, the opening of the air inlet increases, and when the knob controls the firepower to decrease, the opening of the air inlet decreases.

[0012] Preferably, the stove further includes a control unit, which is electrically connected to the angle sensor and the drive mechanism respectively, and controls the drive mechanism to open and close the baffle according to the detection result of the angle sensor.

[0013] Preferably, the drive mechanism includes a linear motor and a pull rod, the pull rod being connected to the baffle.

[0014] Preferably, the drive mechanism includes a solenoid valve and a pull rod, the pull rod being connected to the valve stem of the solenoid valve.

[0015] Preferably, the drive mechanism includes a cylinder and a pull rod, the pull rod being connected to the piston of the cylinder.

[0016] Preferably, the stove further includes a stopcock valve, the knob is connected to the valve stem of the stopcock valve, and the angle sensor is located inside the knob and connected to the valve stem of the stopcock valve.

[0017] Preferably, the cooktop further includes a stopcock valve, the knob is connected to the valve stem of the stopcock valve, the angle sensor includes a detection module and a positioning ring, the positioning ring is arranged around the valve stem, and multiple positioning points are provided on the inner circumference of the positioning ring, the multiple positioning points correspond to the rotation angle of the knob, the detection module is located on the valve stem corresponding to the position of the positioning ring, and is used to identify the multiple positioning points.

[0018] Preferably, the baffle is a box-shaped structure with an opening at the bottom.

[0019] In this design, the baffle is box-shaped, so the baffle only contacts the surface of the bottom shell through its edge, thereby reducing friction and lowering the resistance when pulling.

[0020] Preferably, the baffle has an L-shaped connecting part at one end near the pull rod, and the end of the pull rod has a bent insertion part, which is inserted into the L-shaped connecting part and fixedly connected to the L-shaped connecting part.

[0021] Preferably, the control unit controls the drive mechanism so that the opening degree of the air inlet opened by the baffle changes with the rotation angle of the knob.

[0022] The positive and progressive effects of this utility model are as follows: the angle sensor and the drive mechanism in the stove are electrically connected, so the opening of the baffle can be controlled by detecting the rotation angle of the knob. When the knob controls the firepower to increase, the opening of the air inlet increases, and when the knob controls the firepower to decrease, the opening of the air inlet decreases.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and by way of embodiments, but the present invention is not limited to the scope of the embodiments thereon.

[0032] like Figure 1-7 As shown, this embodiment provides a cooktop 100, which includes: a bottom shell 120, a knob 130, an angle sensor 150, a drive mechanism 160, and a baffle 170; the bottom shell 120 is provided with an air inlet 121, which is opened and closed by the baffle 170; the drive mechanism 160 is used to drive the opening and closing of the baffle 170; the angle sensor 150 is used to detect the rotation angle of the knob 130; and the angle sensor 150 is electrically connected to the drive mechanism 160.

[0033] The angle sensor 150 and the drive mechanism 160 in the stove 100 are electrically connected, so that the opening of the baffle 170 can be controlled by detecting the rotation angle of the knob 130. When the rotation angle of the knob 130 is large, the opening of the air inlet 121 is increased, and when the rotation angle of the knob 130 is small, the opening of the air inlet 121 is decreased.

[0034] The cooktop 100 also includes a glass panel 110, a bottom shell 120 connected to the bottom of the glass panel 110, and a knob 130 located above the glass panel 110.

[0035] The stove 100 in this embodiment uses a glass panel 110 for easy cleaning, but the present invention is not limited to this, and those skilled in the art can also set other materials for the panel as needed.

[0036] The air inlet 121 is located below the inlet of the ejector tube.

[0037] The stove 100 in this embodiment is a dual-burner stove 100, which has two burners. The air inlet 121 is set for each burner, and the opening degree of each air inlet 121 is controlled by the knob 130 corresponding to its respective burner.

[0038] The cooktop 100 also includes a control unit 180, which is electrically connected to the angle sensor 150 and the drive mechanism 160 respectively, and controls the drive mechanism 160 to open and close the baffle 170 according to the detection result of the angle sensor 150.

[0039] The drive mechanism 160 can adopt an existing structure. In this embodiment, the drive mechanism 160 includes a linear motor 161 and a pull rod 162, the pull rod 162 being connected to the baffle 170.

[0040] In another embodiment, the drive mechanism 160 may include a solenoid valve and a lever 162, the lever 162 being connected to the valve stem of the solenoid valve.

[0041] In another embodiment, the drive mechanism 160 includes a cylinder and a lever 162, the lever 162 being connected to the piston of the cylinder.

[0042] The cooktop 100 also includes a stop valve, with a knob 130 connected to the valve stem 140 of the stop valve.

[0043] In this embodiment, the angle sensor 150 includes a detection module and a positioning ring. The positioning ring is arranged around the valve stem 140, and multiple positioning points are provided on the inner circumference of the positioning ring. The multiple positioning points correspond to the rotation angle of the knob 130. The detection module is located on the valve stem 140 at the position corresponding to the positioning ring and is used to identify the multiple positioning points.

[0044] In other embodiments, the angle sensor 150 is located inside the knob 130 and connected to the valve stem 140 of the stopcock valve. This angle sensor 150 is an integral unit, located inside the knob 130 and directly connected to the valve stem 140 to measure the rotation angle of the valve stem 140.

[0045] The baffle 170 is a box-shaped structure with an opening at the bottom. Because the baffle 170 is box-shaped, it only contacts the surface of the bottom shell 120 through its edge, thereby reducing friction and lowering the resistance when pulling.

[0046] In other embodiments, the baffle 170 may also be flat. In other embodiments, a guide member may be provided between the baffle 170 and the upper surface of the bottom shell 120 to ensure that the baffle 170 moves in a straight line so as to facilitate adjustment of the opening of the air inlet 121.

[0047] The baffle 170 has an L-shaped connecting portion 171 near the pull rod 162, and the end of the pull rod 162 has a bent insertion portion 1621. The insertion portion 1621 is inserted into the L-shaped connecting portion 171 and fixedly connected to it. In this embodiment, both the L-shaped connecting portion 171 and the insertion portion 1621 of the pull rod 162 have screw holes, and the two are fixedly connected to each other by screws.

[0048] This embodiment uses an L-shaped connecting part 171 to connect the pull rod 162 and the baffle 170. However, this utility model is not limited to this. Those skilled in the art can realize the connection between the pull rod 162 and the baffle 170 according to needs and other existing structures. The pull rod 162 has a certain degree of elasticity to avoid hard contact under force, which could damage the parts.

[0049] like Figure 7 As shown, the control unit 180 is connected to the angle sensor 150 and the drive mechanism 160 respectively. Specifically, the control unit 180 is electrically connected to the linear motor 161 of the drive mechanism 160, and the control unit 180 controls the rotation of the linear motor 161 according to the detection result of the angle sensor 150.

[0050] The control unit 180 performs logic operations and control. It receives rotation angle information from the angle sensor 150 (valve stem 140), performs logic operations and control, and then outputs commands to the linear motor 161. The linear motor 161 rotates according to the commands, thereby driving the baffle 170 to move. The control unit 180 converts the rotation angle of the valve stem 140 into the movement of the baffle 170 according to the following logic formula:

[0051] Calculation formula: .

[0052] y is the movement of baffle 170, x is the rotation angle of valve stem 140, and k is the opening length of primary air inlet 121.

[0053] The control unit 180 controls the drive mechanism 160 so that the opening of the air inlet 121 by the baffle 170 increases as the rotation angle of the knob 130 increases.

[0054] The linear motor 161 rotates according to the command output by the control unit 180, and drives the baffle 170 to move back and forth through the pull rod 162, thereby realizing the stepless adjustment of the air inlet 121 from fully open to fully closed.

[0055] 1) Overall description of the sport:

[0056] As the knob 130 rotates from 0° to 90°, the angle becomes larger and larger, the movement of the baffle 170 also becomes larger and larger, the primary air intake 121 becomes larger and larger, and the amount of primary air gradually increases. When it reaches 90° (maximum fire), the area of ​​the primary air intake 121 is the largest.

[0057] As the knob 130 rotates from 90° to 180°, the angle continues to increase, the flame gradually decreases, and the movement of the baffle 170 also gradually decreases, which means that the primary air intake 121 becomes smaller and smaller, and the amount of primary air required for combustion becomes less and less.

[0058] When knob 130 is turned back from 180°, the angle continues to decrease and the flame gradually increases. The flame is at its maximum when it reaches 90°. At this time, the movement of baffle 170 is at its maximum, and the primary air intake is at its maximum.

[0059] As knob 130 continues to turn back from 90°, the angle continues to decrease until 0°, the flame gradually decreases, and the flame goes out when it reaches 0°. At this time, the movement of baffle 170 is 0, and baffle 170 completely covers the primary air intake 121.

[0060] 2) With the damper fully closed:

[0061] At this time, the knob 130 is in the closed state, i.e., x=0, y=0, meaning the baffle 170 is not moving and completely covers the primary air intake 121. This state not only prevents insects and rodents from entering the stove 100 and damaging its parts, but also isolates the gas outside the stove 100's bottom shell 120 from the electricity inside, achieving physical separation of gas and electricity, thus ensuring safe use by the user.

[0062] 3) With the damper fully open:

[0063] At this point, the knob 130 has rotated 90°, and the gas stove is in its maximum flame state, i.e., x=π / 2, y=k. The baffle 170 moves by the length of the primary air inlet 121, meaning the baffle 170 has completely moved away from above the primary air inlet 121, leaving the primary air inlet 121 fully open and unobstructed. At this time, the primary air intake is at its maximum, resulting in the most complete combustion and highest efficiency. Simultaneously, the incoming primary air is cold air from outside the bottom shell 120 of the stove 100. This air reduces the temperature rise of internal components, extending their lifespan.

[0064] 4) Damper partially open:

[0065] Taking the valve stem angle as 140° to 45° or 135° as an example, y=3k / 4. At this time, the gas stove is in medium flame mode, and the primary air demand is not as large as in the maximum flame mode. Therefore, this utility model can automatically reduce the air inlet area of ​​the damper to mix with the gas in the optimal ratio, thereby achieving the best combustion state.
