Description

Technical Field

[0001] This utility model relates to the field of gas stove technology, and in particular to an automatic lifting pot support and an open-flame intelligent cooking stove. Background Technology

[0002] Controlling the temperature of open-flame cooking equipment is a significant challenge in the industry. Conventional induction cookers, through silicon controlled rectifiers (SCRs) and intermittent heating, can maintain power around 100W, keeping food at a set temperature for heat preservation. However, to prevent flameouts, the burner on open-flame cooking equipment is typically designed with a higher heat output, generally exceeding 400W to 500W. This makes it impossible to set a very low heat mode for heat preservation. Furthermore, safety regulations prohibit automatic ignition in open-flame cooking equipment, preventing intermittent heating and achieving low-power heat preservation or temperature control. Utility Model Content

[0003] Therefore, it is necessary to provide an automatic lifting pot support and an intelligent open-flame cooking stove to address the problem that current open-flame cooking equipment cannot achieve low-power heat preservation or temperature control.

[0004] On one hand, this application provides an automatic lifting pot support, comprising:

[0005] Fixed base;

[0006] Support assembly;

[0007] The lifting assembly includes two sets of scissor support assemblies disposed between the fixed base and the bracket assembly in a front-back direction. Each scissor support assembly includes a pair of first connecting arms rotatably connected to the left and right sides of the fixed base, a pair of second connecting arms rotatably connected to the left and right sides of the bracket assembly, and a connecting shaft that rotatably connects the first connecting arms and the second connecting arms respectively.

[0008] A drive assembly, drivably connected to the connecting shaft; and

[0009] A control component, comprising a temperature sensing module and a control unit, wherein the temperature sensing module is disposed at the center of the support assembly, and the control unit is communicatively connected to the temperature sensing module and the drive assembly.

[0010] In one embodiment, the drive assembly includes a drive motor, a transmission rod arranged along the front-rear direction, and two transmission members rotatably connected to the two connecting shafts. The transmission rod includes two transmission parts, and the two transmission members are movably disposed in the transmission parts. One of the transmission parts is screwed into the transmission member so that when the drive motor drives the transmission rod to rotate, it drives the transmission part to drive the connecting shaft to translate along the front-rear direction.

[0011] In one embodiment, the two transmission parts are screwed into the two transmission components respectively, and the threads of the two transmission parts are in opposite directions. The openings of the first connecting arm and the second connecting arm of the two sets of scissor support assemblies face different sides.

[0012] In one embodiment, the two transmission parts are screwed into the two transmission components respectively, and the threads of the two transmission parts are in the same direction. The openings of the first connecting arm and the second connecting arm of the two sets of scissor support assemblies face the same side.

[0013] In one embodiment, the support assembly includes a pot support, an upper tray, and a plurality of top rods disposed between the pot support and the upper tray, wherein the second connecting arms are rotatably connected to the upper tray.

[0014] In one embodiment, the bottom of the pot support is provided with multiple positioning grooves, and the top rod is inserted into the positioning grooves respectively.

[0015] In one embodiment, the support assembly further includes a shock-absorbing pad fixed to the upper end of the top rod.

[0016] In one embodiment, the upper end of the top rod is provided with a fitting groove, and the shock-absorbing pad includes a fixing part and a shock-absorbing part extending upward from the fixing part. The fixing part is partially embedded in the fitting groove, and the upper surface of the shock-absorbing part is higher than the upper end surface of the top rod.

[0017] In one embodiment, the support assembly further includes a liquid-holding tray having a plurality of through holes, into which the push rods are respectively inserted.

[0018] On the other hand, this application also provides an open-flame intelligent cooking stove, including:

[0019] The stove body has a burner head;

[0020] As described above, the automatic lifting pot support is installed on the stove body, and the support assembly of the automatic lifting pot support is located above the burner head.

[0021] In summary, the automatic lifting pot support of this application utilizes a support assembly for height adjustment, enabling control of the distance between the pot bottom and the flame, and regulating the heat received by the pot. This allows for different power outputs based on varying distances, solving the problem of open-flame cooking equipment being unable to achieve low heat and low power. Furthermore, this application utilizes a temperature sensing module and control unit to automatically adjust the height of the support assembly based on the pot bottom temperature, thus automatically adjusting the distance between the pot bottom and the flame, achieving constant temperature and temperature control technology in intelligent cooking.

[0037] Addressing the limitations of current open-flame cooking equipment in achieving low-power heat preservation or temperature control, this application provides an automatic lifting pot support and an intelligent open-flame cooking stove. Utilizing the automatic lifting pot support of this application, the intelligent open-flame cooking stove can achieve low-power gas heating.

[0038] Specifically, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This application provides an automatic lifting pot support 100, which may include a fixed base 10, a support assembly 20, a lifting assembly 30, a drive assembly 40, and a control assembly. The fixed base 10 can be fixed to the stove body 200 of an open-flame intelligent cooking stove, and the support assembly 20 can be used to support the pot body. The lifting assembly 30 may include two sets of scissor support assemblies 31, which are arranged in a front-to-back direction between the fixed base 10 and the support assembly 20. Each set of scissor support assemblies 31 includes a pair of first connecting arms 311, a pair of second connecting arms 312, and a connecting shaft 313. The two first connecting arms 311 are rotatably connected to the left and right sides of the fixed base 10, and the two second connecting arms 312 are rotatably connected to the left and right sides of the support assembly 20. The connecting shaft 313 rotatably connects the first connecting arms 311 and the second connecting arms 312. The drive assembly 40 is drivably connected to the connecting shaft 313 and can drive the connecting shaft 313 to translate in the front-back direction, so that the first connecting arm 311 and the second connecting arm 312 can be extended or retracted.

[0039] like Figure 3 and Figure 4 As shown, when the first connecting arm 311 and the second connecting arm 312 are extended, the support assembly 20 is raised by the first connecting arm 311 and the second connecting arm 312. When the first connecting arm 311 and the second connecting arm 312 are retracted, the support assembly 20 is lowered by the first connecting arm 311 and the second connecting arm 312. The control assembly includes a temperature sensing module 50 and a control unit. The temperature sensing module 50 is located at the center of the support assembly 20 and can be used to detect the temperature of the pot bottom. The control unit is communicatively connected to the temperature sensing module 50 and the drive assembly 40, and can control the drive assembly 40 according to the temperature of the pot bottom, so that the drive assembly 40 controls the height of the support assembly 20.

[0040] Understandably, with the inner and outer ring burner caps of the burner head 210 remaining stationary, the temperature of the pot bottom is related to the distance between the flame and the pot. Therefore, this application utilizes the support assembly 20 for height adjustment to control the distance between the pot bottom and the flame, thereby adjusting the heat received by the pot and achieving different power outputs based on different distances. This solves the problem that open-flame cooking equipment cannot achieve low heat and low power. Furthermore, this application utilizes the temperature sensing module 50 and the control unit to automatically adjust the height of the support assembly 20 based on the pot bottom temperature, thus automatically adjusting the distance between the pot bottom and the flame, enabling constant temperature and temperature control technology in intelligent cooking.

[0041] For example, when cooking braised dishes or foods prone to overflowing, high heat can be used initially. When the temperature sensing module 50 detects that the water temperature converted from the pot bottom temperature has reached the set temperature, the control module controls the drive component 40 to start, moving the pot body a certain distance away from the flame to achieve low-heat heating. The distance between the pot bottom and the flame can be set according to the power of the burner 210. For example, a stroke of 5mm to 30mm corresponds to a power of 500W to 100W respectively. Depending on different needs, the control bracket component 20 rises different distances, thereby achieving the purpose of controlling the power of the open flame cooking equipment.

[0042] More specifically, such as Figure 5As shown, in some embodiments, the drive assembly 40 may include a drive motor 41, a transmission rod 42, and two transmission components 43. The transmission rod 42 is arranged in the front-to-back direction and includes two transmission parts 421. The two transmission components 43 are respectively movably disposed on the transmission parts 421 and rotatably connected to the two connecting shafts 313. One of the transmission parts 421 is screwed into the transmission component 43. Thus, when the drive motor 41 drives the transmission rod 42 to rotate, the transmission part 421 screwed into the transmission rod 42 moves forward or backward under the action of the thread, thereby driving the connecting shaft 313 to move forward or backward, causing the bracket assembly 20 to rise or fall. The other transmission component 43 is driven by the other connecting shaft 313 to slide along the transmission rod 42, which can play a guiding role and make the raising and lowering of the bracket assembly 20 more stable.

[0043] Optionally, in some embodiments, the two transmission parts 421 are screwed into the two transmission components 43 respectively, and the threads of the two transmission parts 421 are in opposite directions. The openings of the first connecting arms 311 and the second connecting arms 312 of the two sets of scissor support assemblies 31 face different sides. In this way, when the electric drive transmission rod 42 is driven to rotate, the two transmission parts 421 move closer or further away from each other simultaneously under the action of the threads in opposite directions. If the openings of the first connecting arms 311 and the second connecting arms 312 are both facing outwards, when the two transmission parts 421 move away from each other, the first connecting arms 311 and the second connecting arms 312 unfold, causing the support assembly 20 to rise; when the two transmission parts 421 move closer to each other, the first connecting arms 311 and the second connecting arms 312 retract, causing the support assembly 20 to fall. If the openings of the first connecting arm 311 and the second connecting arm 312 both face inward, when the two transmission parts 421 approach each other, the first connecting arm 311 and the second connecting arm 312 retract, causing the support assembly 20 to rise; when the two transmission parts 421 move away from each other, the first connecting arm 311 and the second connecting arm 312 unfold, causing the support assembly 20 to fall.

[0044] In some embodiments, the two transmission parts 421 are screwed into the two transmission members 43 respectively, and the threads of the two transmission parts 421 are in the same direction. The openings of the first connecting arms 311 and the second connecting arms 312 of the two sets of scissor support assemblies 31 face the same side. Thus, when the electric drive transmission rod 42 is driven to rotate, the two transmission parts 421 move forward or backward simultaneously under the action of the threads in the same direction. If the openings of the first connecting arms 311 and the second connecting arms 312 are both facing forward, when the two transmission parts 421 move forward, the first connecting arms 311 and the second connecting arms 312 unfold, causing the support assembly 20 to rise; when the two transmission parts 421 move backward, the first connecting arms 311 and the second connecting arms 312 retract, causing the support assembly 20 to fall. If the openings of the first connecting arm 311 and the second connecting arm 312 both face the rear, when the two transmission parts 421 move forward, the first connecting arm 311 and the second connecting arm 312 retract, causing the support assembly 20 to descend; when the two transmission parts 421 move backward, the first connecting arm 311 and the second connecting arm 312 unfold, causing the support assembly 20 to rise.

[0045] Preferably, the openings of the first connecting arm 311 and the second connecting arm 312 both face outwards, so that when the first connecting arm 311 and the second connecting arm 312 are retracted, the connecting shaft 313 is stored between the fixed base 10 and the bracket assembly 20, which saves more space.

[0046] For example, in some embodiments, the two transmission parts 421 of the transmission rod 42 can be two screws respectively, and the transmission member 43 is a nut that cooperates with the two screws respectively.

[0047] like Figure 3 and Figure 6 As shown, in some embodiments, the support assembly 20 may include a pot support 21, an upper tray 22, and a plurality of push rods 23. The plurality of push rods 23 are respectively disposed between the pot support 21 and the upper tray 22, and the second connecting arms 312 are rotatably connected to the upper tray 22. In this way, the push rods 23 separate the pot support 21 and the upper tray 22, so that a space for accommodating the burner head 210 is formed between the pot support 21 and the upper tray 22. When the first connecting arm 311 and the second connecting arm 312 are driven to unfold, the upper tray 22 is raised, thereby driving the pot support 21 to rise through the push rods 23. When the first connecting arm 311 and the second connecting arm 312 are driven to retract, the upper tray 22 is lowered, thereby driving the pot support 21 to fall through the push rods 23.

[0048] like Figure 6 and Figure 7 As shown, in some embodiments, the bottom of the pot support 21 is provided with multiple positioning grooves 211, and the top rods 23 are respectively inserted into the positioning grooves 211. In this way, the pot support 21 can be freely removed and taken off, which is convenient for cleaning and replacing the pot support 21.

[0049] Furthermore, such as Figure 7 As shown, in some embodiments, the support assembly 20 further includes a shock-absorbing pad 24, which is fixed to the upper end of the top rod 23. The shock-absorbing pad 24 can be used to absorb the impact generated during the raising and lowering of the support assembly 20, allowing the pot support 21 to rise or fall more smoothly.

[0050] Preferably, such as Figure 7 As shown, in some embodiments, the upper end of the top rod 23 is provided with a fitting groove 231, and the shock-absorbing pad 24 includes a fixing part 241 and a shock-absorbing part 242 extending upward from the fixing part 241. The fixing part 241 is partially embedded in the fitting groove 231, so that the shock-absorbing pad 24 is more firmly fixed to the upper end of the top rod 23. The upper surface of the shock-absorbing part 242 is higher than the upper end surface of the top rod 23. In this way, when the pot support 21 is placed on the top rod 23, the pot support 21 first contacts the shock-absorbing part 242, and the shock-absorbing part 242 deforms and then contacts the top rod 23. This can reduce the rigid contact between the pot support 21 and the top rod 23 and reduce the impact generated by the pot support 21 during the lifting and lowering process.

[0051] In particular, such as Figure 6 and Figure 8 As shown, in some embodiments, the support assembly 20 further includes a liquid collection tray 25, which has multiple through holes 251, and a push rod 23 is inserted into each of the through holes 251. The liquid collection tray 25 can be installed on the stove body 200 to collect liquids such as soup and broth produced during cooking. By providing multiple through holes 251 on the liquid collection tray 25 and using the push rod 23 and the through holes 251 for positioning, it is convenient to disassemble and install the liquid collection tray 25, and to facilitate subsequent cleaning and replacement of the liquid collection tray 25.

[0052] On the other hand, such as Figure 1 and Figure 2 As shown, this application also provides an open-flame intelligent cooking stove, which may include a stove body 200 and an automatic lifting pot support 100 as described above. The stove body 200 has a burner head 210, and the automatic lifting pot support 100 is installed on the stove body 200, with its support assembly 20 located above the burner head 210. This open-flame intelligent stove utilizes the automatic lifting pot support 100 to adjust the distance between the pot body and the burner head 210, achieving constant temperature and temperature control technology in intelligent cooking.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
