Description

Technical Field

[0001] This utility model relates to the field of commercial kitchen equipment technology, specifically to a control device for a commercial stove. Background Technology

[0002] Commercial stoves have control devices installed on their control panels for ignition, flameout, and flame size control. Flame size control is typically achieved using a rotary adjustment mechanism. The advantage of this mechanism is its intuitiveness and convenience. However, the back of the rotary adjustment mechanism is relatively thin because it is directly fixed to the circuit board. During rotation, the force is applied directly to the rotary potentiometer, making the adjustment mechanism prone to damage. Repairs usually require replacing the entire controller, which is both troublesome and costly. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a control device for commercial stoves, thus solving the problems existing in the prior art.

[0004] The technical solution is as follows: a control device for a commercial stove, including a rotary regulator with a knob, a rotating device and a housing, the rotary regulator being fixed to the housing by a fixing nut, the knob being installed through the housing, the knob being mounted on the rotating device, the rotating device having a permanent magnet concentric with the knob, and the permanent magnet being attracted to the fixing nut.

[0005] Based on the above technical solution, a further optimization is made: a mounting part is provided at the center of the rotating device; the permanent magnet is fixedly mounted on the surface of the mounting part; the knob passes through the permanent magnet; a knob hole is opened at the center of the mounting part; the knob is installed in the knob hole; an inner positioning part is provided in the knob hole; an outer positioning part is provided on the outside of the knob; and the outer positioning part is restricted to be installed in the inner positioning part.

[0006] Based on the above technical solution, the width of the knob hole is greater than the width of the knob, and the knob can move within the radial range of the knob hole to maintain the concentricity between the knob and the rotating device.

[0007] Based on the above technical solution, a positioning bushing is further optimized, wherein the rotating device is provided with a positioning bushing, the positioning bushing is concentrically arranged with the knob, and a fixed shaft is provided on the housing, and the positioning bushing rotates along the fixed shaft.

[0008] Based on the above technical solution, a further optimization is made by providing a protruding limiting block on the housing, the limiting block being arranged around the knob, and a limiting plate being arranged around the outer side of the positioning bushing.

[0009] Based on the above technical solution, further optimization is made by setting the limiting block around the circumference of the fixed axis, setting at least one limiting plate, and setting the limiting plate to rotate within the circumferential area defined by the limiting block.

[0010] Based on the above technical solution, the housing includes a panel, the knob passes through the panel, the fixing nut fixes the rotary potentiometer on the panel, the fixing shaft is fixedly disposed on the surface of the panel, and the limiting block is disposed on the surface of the panel.

[0011] Based on the above technical solution, a further optimization is made by providing a cover on the rotating device, which encloses the positioning bushing, and the limiting plate connects the inner wall of the cover and the outer wall of the positioning bushing.

[0012] Based on the above technical solution, a handle is further optimized by providing a grip on the upper part or around the rotating device.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] The design is reasonable. A permanent magnet on the rotating device engages with a fixed nut on the panel. The axial force is applied to both the permanent magnet and the fixed nut, and the attraction between them increases rotational resistance, reducing the possibility of accidental activation. The rotating device is easy to disassemble and maintain, and is not prone to falling off. The fixed shaft on the panel and the positioning sleeve on the rotating device work together to achieve rotation. During rotation, the circumferential force is directly applied to the fixed shaft and the positioning sleeve. The rotary adjuster rotates with the positioning sleeve, minimizing the force applied at one point. A limit block is installed on the panel, and a limit plate is installed on the rotating device. The limit plate restricts the rotation angle within the circumferential range of the limit block, preventing over-rotation of the rotating device and reducing the rotation cycle of the adjustment knob. This device significantly extends its service life, reduces maintenance time and costs, and improves work efficiency. Attached Figure Description

[0028] Reference Figure 1-9 A control device for a commercial stove includes a rotary regulator with a knob 3, a rotating device 1, and a housing 2. The rotary regulator is fixed to the housing 2 by a fixing nut 4. The knob 3 is installed through the housing 2 and mounted on the rotating device 1. The rotating device 1 has a permanent magnet 5 concentric with the knob 3, which is attracted to the fixing nut 4. A mounting part 14 is provided at the center of the rotating device 1, and the permanent magnet 5 is fixedly mounted on the surface of the mounting part 14. The knob 3 passes through the permanent magnet 5. A knob hole 15 is provided at the center of the mounting part 14, and the knob 3 is installed in the knob hole 15. An inner positioning part 151 is provided inside the knob hole 15, and an outer positioning part 31 is provided outside the knob 3, which is confined within the inner positioning part 151. The width of the knob hole 15 is greater than the width of the knob 3, allowing the knob 3 to move within the radial range of the knob hole 15, thus maintaining the concentricity between the knob 3 and the rotating device 1. A positioning sleeve 13 is provided on the rotating device 1, and the positioning sleeve 13 is concentrically arranged with the knob 3. A fixed shaft 23 is provided on the housing 2, and the positioning sleeve 13 rotates along the fixed shaft 23. A protruding limiting block 22 is provided on the housing 2, and the limiting block 22 is arranged around the knob 3. A limiting plate 12 is arranged around the outer side of the positioning sleeve 13. The limiting block 22 is arranged around the circumference of the fixed shaft 23. At least one limiting block 22 and a limiting plate 12 are provided respectively, and the limiting plate 12 rotates within the circumferential area defined by the limiting block 22. If two or more limiting blocks 22 are provided, the limiting plate 12 rotates between two adjacent limiting blocks 22. The circumferential distance between the two limiting blocks 22 is set, that is, the rotating device 1 is set to rotate within the adjustment area given by the limiting blocks 22. The housing 2 includes a panel 21, a knob 3 passing through the panel 21, a fixing nut 4 fixing a rotary potentiometer to the panel 21, a fixing shaft 23 fixedly disposed on the surface of the panel 21, and a limiting block 22 disposed on the surface of the panel 21.

The knob 3 is positioned and installed in the knob hole 15. The positioning sleeve 13 surrounds the outside of the fixed shaft 23. When the handle 16 is rotated, the cover 11 rotates, which drives the knob 3 positioned thereto to rotate. The positioning sleeve 13 rotates along the fixed shaft 23. A permanent magnet 5 with a hole is provided on the mounting part 14. The knob 3 passes through the hole, and the permanent magnet 5 is attracted to the fixing nut 4 of the fixed rotary adjuster and rotates on its surface. The size of the knob hole 15 is slightly larger than the size of the knob 3, that is, the knob 3 can move slightly in the knob hole 15, so that the knob 3 and the rotating device 1 always maintain concentricity, thereby reducing the axial and radial forces on the knob 3.

[0030] The housing 2 in this device is mounted on the stove, and its structure is not limited to that shown in the figure. It can be any shape that works in conjunction with the rotating device 1.

[0031] Any unmentioned structures and connections are common knowledge.
