Description

Technical Field

[0001] This application relates to the technical field of kitchen utensils, and particularly to a heat - concentrating disc for a gas stove. Background Art

[0002] The heat - concentrating disc can be used to improve the thermal efficiency of a gas stove. Generally, the heat - concentrating disc can generally improve the thermal efficiency by 2 - 3 percentage points.

[0003] When the gas stove is working, gas enters the stove from the gas inlet pipe, is regulated by the gas valve and enters the burner head, while mixing with a part of air. This part of air is called primary air. These mixed gases are ejected from the flame holes of the burner and are ignited by the ignition device to form flames. The air required for combustion is called secondary air. These flames are used to heat the cookware placed on the pot support.

[0004] Although ordinary heat - concentrating discs significantly improve the performance of gas stoves, they will affect the supply of secondary air to the combustion system. Whether the supply of secondary air is sufficient is related to whether the combustion is complete, and problems such as excessive release of carbon monoxide.

[0005] In addition, due to differences in gas sources in different regions, there are differences in gas pressure, calorific value, etc. Ordinary heat - concentrating discs cannot take into account the supply of secondary air under different flame states, but will instead affect the performance of the product.

[0029] The following are specific embodiments of the present application in combination with the drawings to further describe the technical solutions of the present application, but the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided only to help fully understand the embodiments of the present application. Therefore, those skilled in the art should clearly understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Additionally, descriptions of known functions and structures are omitted for clarity and conciseness.

[0030] The present application provides a heat - collecting disk for a gas stove, which can take into account the secondary air supply under different flame states.

[0031] The following further explains and illustrates the heat - collecting disk for a gas stove shown in the embodiments of the present application with reference to the accompanying drawings.

[0032] Reference Figures 1 to 4 , the heat - collecting disk for a gas stove includes: an upper disk body 10, a first lower disk piece 21, a second lower disk piece 22, a third lower disk piece 23, a fourth lower disk piece 24, an elastic connection member 30, a transmission member 40, and a driving mechanism 50; four slots 11 for embedding the support feet 60 of the stove rack are evenly arranged along the circumferential direction at the lower end of the upper disk body 10, and four lower ends 12 are correspondingly formed between the slots 11; the first lower disk piece 21, the second lower disk piece 22, the third lower disk piece 23, and the fourth lower disk piece 24 are rotatably connected to the four lower ends 12 along the circumferential direction of the upper disk body 10 in sequence; among them, the first lower disk piece 21 and the second lower disk piece 22 are connected together by an elastic connection member 30; the third lower disk piece 23 and the fourth lower disk piece 24 are connected together by an elastic connection member 30; the second lower disk piece 22 and the third lower disk piece 23 are respectively rotatably connected to both ends of the transmission member 40; the driving mechanism 50 is connected to the transmission member 40 to adjust the angle between each lower disk piece and the upper disk body 1 through the transmission member 40.

[0033] Specifically, the driving mechanism 50 acts on the second lower disk piece 22 and the third lower disk piece 23 through the transmission member 40, causing the second lower disk piece 22 and the third lower disk piece 23 to rotate around the upper disk body 1. The second lower disk piece 22 drives the first lower disk piece 21 to rotate synchronously through the elastic connection member 30; the third lower disk piece 23 drives the fourth lower disk piece 24 to rotate synchronously. Therefore, under the drive of the driving mechanism 50, the four lower disk pieces rotate.

[0034] The air for secondary supply enters from the gap between the lower end of the lower disk piece and the stove rack. By adjusting the angle of the lower disk piece, the width of the gap is adjusted to meet the secondary air supply under different flame states. Whether the secondary air is supplemented sufficiently is related to issues such as whether the combustion is complete and the release of excessive carbon monoxide. By adjusting the angular positions of the four lower disk pieces, the heat - collecting disk for a gas stove can meet the secondary air supply of the gas stove under different flame states; the heat - collecting disk for a gas stove takes into account both the performance of the gas stove and the secondary air supply of the combustion system.

[0035] It should be noted that during the rotation of the lower disk, the relative positions between the first lower disk 21 and the second lower disk 22 will change. The elastic connection member 30 adapts to these changes in position relationships through elastic deformation during the rotation of the lower disk and drives the first lower disk 21 to rotate synchronously. Similarly, the elastic connection member 30 between the third lower disk 23 and the fourth lower disk 24 will also undergo elastic deformation during rotation.

[0036] In addition, the transmission member 40 between the second lower disk 22 and the third lower disk 23 can also deform to adapt to the change in the relative position relationship between the second lower disk 22 and the third lower disk 23.

[0037] Reference Figure 4 , the driving mechanism 50 includes a motor 51, a disk 52, a first connecting rod 53, and a second connecting rod 54; the disk 52 is fixed on the output shaft of the motor 51; one end of the first connecting rod 53 is rotatably connected to a connection point on the disk 52, and the other end is connected to one end of the second connecting rod 54; the second connecting rod 54 is connected to the transmission member 40.

[0038] The above is a specific implementation manner of the driving mechanism 50. In this implementation manner, the motor 51 drives the lower disk to rotate through the disk 52, the first connecting rod 53, the second connecting rod 54, and the transmission member 40.

[0039] In some embodiments, the second connecting rod 54 is detachably connected to the transmission member 40. The detachable connection between the second connecting rod 54 and the transmission member 40 facilitates cleaning.

[0040] Reference Figure 5 , the transmission member 40 has a connection portion 41 for cooperating with the second connecting rod 54; a longitudinally penetrating longitudinal groove 41a for engaging the second connecting rod 54 is provided on the connection portion 41; the second connecting rod 54 is provided with a laterally penetrating lateral groove 54a for engaging the transmission member 40.

[0041] The second connecting rod 54 and the transmission member 40 are mutually engaged in each other's grooves. When disassembly is required, it only needs to pull out the transmission member 40 from the second connecting rod 54, and the operation is simple.

[0042] Furthermore, the motor 51 is a servo motor; the servo motor is controlled by a controller. The controller can control the angular position of the lower disk by controlling the motor 51 to adjust the secondary air supply of the combustion system.

[0043] Furthermore, the servo motor controls the angle between the lower disk and the upper disk body 10 according to the rotation angle of the regulating valve of the gas stove.

[0044] It should be noted that the rotation angle of the gas stove regulating valve is used to indicate the gas flow rate.

[0045] In some embodiments, the upper disk body 1 is connected to each lower disk piece through a rotating connecting member 70;

[0046] Reference Figure 7 , the rotating connecting member 70 has a rotating joint 71, and both ends of the rotating joint 71 respectively have a fixing portion 72, which are respectively fixed on the upper disk body 10 and the lower disk piece.

[0047] Reference Figure 6 , the elastic connecting member 30 includes fitting connecting portions 31 located at both ends, and an elastic bending portion 32 located between the two fitting connecting portions 31;

[0048] The two fitting connecting portions 31 are respectively fitted and fixed on the outer surfaces of the two side lower disk pieces; the elastic bending portion 32 bends outward to bypass the stove rack support feet.

[0049] It should be noted that on the one hand, the elastic bending portion 32 bypasses the stove rack support feet in space, and on the other hand, it can be used to generate elastic deformation during the rotation process.

[0050] In some embodiments, the transmission member 40 includes support feet 42 located at both ends, and a main body portion 43 between the two support feet 42; the support feet 42 at both ends are respectively rotationally connected to the second lower disk piece 22 and the third lower disk piece 23; the connecting portion 41 is arranged on the main body portion 43.

[0051] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art to which the present application pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
