Description

TECHNICAL FIELD

[0001] The present application relates to the field of cooking range, in particular to a multifunctional cooking range. BACKGROUND

[0002] The gas seat is provided with a gas chamber, an inner flame groove, an outer flame groove, an outer flame gas pipe and an inner flame gas pipe. The gas first enters the gas chamber. The two ends of the outer flame gas pipe are respectively communicated to the gas chamber and the outer flame groove. The two ends of the inner flame gas pipe are respectively communicated to the gas chamber and the inner flame groove. The gas first enters the gas chamber, and then is divided into the inner flame groove and the outer flame groove according to the pipe diameter ratio of the outer flame gas pipe and the inner flame gas pipe for combustion.

[0003] On the one hand, the pipe diameter of the outer flame gas pipe and the inner flame gas pipe cannot be adjusted. On the other hand, it is not suitable to install a flow valve on the outer flame gas pipe and the inner flame gas pipe in a high temperature environment. This results in that the fire size ratio of the inner flame groove and the outer flame groove is always relatively fixed and cannot be adjusted. SUMMARY

[0004] Therefore, it is necessary to provide a multifunctional cooking range aiming at the problem that the fire size ratio of the inner flame groove and the outer flame groove cannot be adjusted.

[0005] A multifunctional cooking range comprises:

[0006] A gas seat is provided with an outer flame gas pipe, an inner flame gas pipe and a gas chamber. One end of the outer flame gas pipe and one end of the inner flame gas pipe are communicated to the gas chamber. The other end of the outer flame gas pipe and the other end of the inner flame gas pipe are located outside the gas chamber. A first ozone inlet is formed on the side wall of the outer flame gas pipe. A second ozone inlet is formed on the side wall of the inner flame gas pipe.

[0007] A valve assembly is used to control the on-off of the first ozone inlet and / or the second ozone inlet. A third ozone inlet is formed on the valve assembly.

[0008] A cabinet is provided with a first opening. A first baffle is movably arranged at the first opening.

[0009] An ultraviolet lamp is arranged on the first baffle. The ultraviolet lamp has a disinfection state and a combustion supporting state. When the ultraviolet lamp is in the disinfection state, the ultraviolet lamp is located in the cabinet, and the first baffle is shielded at the first opening. When the ultraviolet lamp is in the combustion supporting state, the first opening is communicated to the valve assembly or the ultraviolet lamp is located outside the cabinet to allow ozone to be introduced into the third ozone inlet.

[0010] The first opening of the present invention is covered with a cover, and the cover has a first ozone outlet, which is connected to the third ozone inlet. When the ultraviolet lamp is in a combustion-supporting state, the ultraviolet lamp is at least partially located inside the cover.

[0011] The cover of the present invention has an air vent, and a one-way valve is provided at the air vent.

[0012] The multi-functional stove of the present invention also includes a control board and a drive device. The drive device drives the first baffle. A temperature sensor is installed at the gas seat. The one-way valve, the valve assembly, the temperature sensor, the ultraviolet lamp and the drive device are all electrically connected to the control board.

[0013] The valve assembly of the present invention includes a valve seat and a valve core;

[0014] The valve seat is provided with a rotating cavity. The third ozone inlet is located on the side wall of the valve seat. The side wall of the valve seat is also provided with a second ozone outlet and a third ozone outlet. The third ozone inlet, the third ozone outlet and the second ozone outlet are all connected to the rotating cavity. The second ozone outlet is connected to the first ozone inlet. The third ozone outlet is connected to the second ozone inlet.

[0015] The valve core is rotatably disposed in the rotating cavity and has a first angle state, a second angle state, and a third angle state. When the valve core is in the first angle state, the third ozone inlet is simultaneously connected to the second ozone outlet and the third ozone outlet. When the valve core is in the second angle state, the valve core simultaneously blocks the space between the second ozone outlet and the third ozone inlet, as well as between the third ozone outlet and the third ozone inlet. When the valve core is in the third angle state, the third ozone inlet and the third ozone outlet are connected, and the valve core blocks the space between the second ozone outlet and the third ozone inlet.

[0016] The valve seat of the present invention has a first axis, and the valve seat includes a first U-shaped plate, a second U-shaped plate, a third U-shaped plate and a fourth U-shaped plate. The first U-shaped plate, the second U-shaped plate, the third U-shaped plate and the fourth U-shaped plate all extend axially along the first axis and are connected sequentially circumferentially along the first axis to form the rotating cavity. The second ozone outlet is located on the first U-shaped plate, the third ozone outlet is located on the second U-shaped plate, the third ozone inlet is located on the third U-shaped plate, and the valve core is provided with an avoidance notch.

[0017] A first side edge is formed at the connection between the first U-shaped plate and the second U-shaped plate, a second side edge is formed at the connection between the second U-shaped plate and the third U-shaped plate, a third side edge is formed at the connection between the third U-shaped plate and the fourth U-shaped plate, and a fourth side edge is formed at the connection between the first U-shaped plate and the fourth U-shaped plate.

[0018] When the valve core is in the first angle state, the valve core abuts against the third side edge and the fourth side edge, and the valve core is provided at intervals on the first side edge and the second side edge through the clearance notch;

[0019] When the valve core is in the second angle state, the valve core abuts against the second side edge and the third side edge, and the valve core is disposed at intervals between the first side edge and the fourth side edge through the clearance notch;

[0020] When the valve core is in the third angle state, the valve core abuts against the first side edge, the third side edge and the fourth side edge, and the valve core is disposed at intervals on the second side edge through the avoidance notch.

[0021] The valve core of the present invention is columnar, the cross-section of the valve core is fan-shaped, and the central angle corresponding to the cross-section of the valve core is greater than 180°.

[0022] The valve assembly of the present invention further includes a first end cap, which is fixed to the end of the rotating cavity. The first end cap has a first circular hole with the same outer diameter as the valve core. The valve core is inserted into the first circular hole. A sealing cap is provided at the end of the valve core. The sealing cap fits against the first end cap to cover the first circular hole.

[0023] The valve assembly of the present invention further includes a second end cap, which is fixed to the end of the rotating cavity opposite to the first end cap. A support shaft is provided on the inner wall of the valve core, and the support shaft passes through the sealing cover and the second end cap.

[0024] The gas holder of the present invention is further provided with an inner flame groove and an outer flame groove. The outer flame groove is arranged around the outside of the inner flame groove. The end of the inner flame gas pipe located outside the gas chamber is connected to the inner flame groove, and the end of the outer flame gas pipe located outside the gas chamber is connected to the outer flame groove.

[0025] The beneficial effects of this invention are as follows:

[0026] When the UV lamp is in disinfection mode, it is located inside the cabinet and can disinfect the dishes inside the cabinet.

[0027] When the UV lamp is in combustion-supporting mode, there are two scenarios: first, the first baffle does not completely block the first opening, allowing the first opening to connect to the third ozone inlet; second, the UV lamp is located outside the cabinet. In both scenarios, the ozone generated by the UV lamp's irradiation flows to the third ozone inlet and enters the valve assembly. The valve assembly can choose not to supply ozone to the first and second ozone inlets, or it can supply ozone to only one of the first and second ozone inlets, or it can supply ozone to both of them simultaneously. Ozone can significantly increase the flame intensity after gas ignition. Therefore, when only one of the first and second ozone inlets supplies ozone, the flame intensity at the inner or outer flame slot can be significantly altered, thereby changing the flame intensity ratio between the two locations.

[0056] Example:

[0057] This embodiment provides a multi-functional stove with disinfection and ignition functions.

[0058] See Figures 1-4 and Figure 18 The multi-functional stove includes a gas socket 1, a valve assembly 2, a cabinet 3, and an ultraviolet lamp 4.

[0059] See Figures 5-8The gas holder 1 is equipped with an outer flame gas pipe 11, an inner flame gas pipe 12, a gas chamber 13, an inner flame groove 14, and an outer flame groove 15. The outer flame groove 15 is arranged around the outside of the inner flame groove 14. The two ends of the outer flame gas pipe 11 are connected to the outer flame groove 15 and the gas chamber 13, respectively. The two ends of the inner flame gas pipe 12 are connected to the inner flame groove 14 and the gas chamber 13, respectively. The gas pipeline is connected to the gas chamber 13, and the gas is split in the gas chamber 13 to the inner flame groove 14 and the outer flame groove 15 for ignition. Accordingly, the ratio of the flame intensity at the inner flame groove 14 and the outer flame groove 15 is largely determined by the ratio of the gas flow rate of the outer flame gas pipe 11 and the inner flame gas pipe 12. An important factor determining the ratio of the gas flow rate of the outer flame gas pipe 11 and the inner flame gas pipe 12 is the pipe diameter ratio between the outer flame gas pipe 11 and the inner flame gas pipe 12. However, the diameter ratio of the outer flame gas pipe 11 and the inner flame gas pipe 12 cannot be changed. At the same time, both the outer flame gas pipe 11 and the inner flame gas pipe 12 are relatively close to the flame and are located at high temperatures. If flow valves are installed on the outer flame gas pipe 11 and the inner flame gas pipe 12, the flow valves are likely to fail. Therefore, the ratio of the firepower at the inner flame slot 14 and the outer flame slot 15 is difficult to adjust or change by controlling the gas flow.

[0060] See Figure 17 and Figure 18 The top of cabinet 3 has a first opening 31, and a first baffle 32 is rotatably installed at the first opening 31. An ultraviolet lamp 4 is mounted on the first baffle 32, thus enabling the ultraviolet lamp 4 to function in both disinfection and combustion-supporting modes. (See also...) Figures 9-12 A third ozone inlet 21 is provided on valve assembly 2. (See also...) Figure 3 Valve assembly 2 is installed on the top of cabinet 3.

[0061] See Figure 20 When the ultraviolet lamp 4 is in disinfection mode, it is located inside the cabinet 3, and the first baffle 32 blocks the first opening 31. The ultraviolet lamp 4 can disinfect the dishes inside the cabinet 3. At the same time, the oxygen inside the cabinet 3 is converted into ozone under ultraviolet irradiation. However, due to the blocking effect of the first baffle 32, the ozone inside the cabinet 3 cannot flow out from the first opening 31, and therefore cannot flow into the third ozone inlet 21.

[0062] See Figure 18 and Figure 19 When the ultraviolet lamp 4 is in combustion-supporting mode, there are two scenarios: First, the first baffle 32 does not completely block the first opening 31, allowing the first opening 31 to connect to the third ozone inlet 21. Second, the ultraviolet lamp 4 is located outside the cabinet 3. In both scenarios, the ozone generated by the ultraviolet irradiation of the ultraviolet lamp 4 can flow to the third ozone inlet 21 and enter the valve assembly 2. See again. Figures 5-8In this embodiment, a first ozone inlet 111 is provided on the side wall of the outer flame gas pipe 11, and a second ozone inlet 121 is provided on the side wall of the inner flame gas pipe 12. The valve assembly 2 may not introduce ozone into the first ozone inlet 111 and the second ozone inlet 121, may introduce ozone into only one of the first ozone inlet 111 and the second ozone inlet 121, or may introduce ozone into both the first ozone inlet 111 and the second ozone inlet 121 simultaneously. Ozone can significantly increase the flame intensity after the gas is ignited. Therefore, when only one of the first ozone inlet 111 and the second ozone inlet 121 is introduced with ozone, the flame intensity at the inner flame groove 14 or the outer flame groove 15 can be significantly changed, thereby changing the ratio of the flame intensity at the two positions of the inner flame groove 14 and the outer flame groove 15.

[0063] See Figures 3-4 , Figures 17-20 A cover 33 is provided at the first opening 31, and a first ozone outlet 331 is provided on the cover 33. The first ozone outlet 331 is connected to the third ozone inlet 21. See also Figure 18 and Figure 19 When the ultraviolet lamp 4 is in combustion-supporting mode, it is at least partially located inside the housing 33. Due to the obstruction and restriction of the housing 33, the ozone generated by the ultraviolet lamp 4 can only flow to the third ozone inlet 21 for combustion support or for disinfection within the cabinet 3. Therefore, the housing 33 effectively prevents ozone waste.

[0064] See Figure 19 The process of oxygen converting into ozone and the process of ozone entering valve assembly 2 will cause a decrease in the internal pressure of housing 33. (See also...) Figure 3 The housing 33 is provided with an air exchange port 34, and a one-way valve is provided at the air exchange port 34. Based on the pressure difference between the inside and outside of the housing 33, the air outside the housing 33 can automatically enter the housing 33 through the air exchange port 34 to continuously replenish the oxygen inside the housing 33, thereby allowing ozone to flow into the valve assembly 2 for a long time.

[0065] Preferably, in this embodiment, the multi-functional stove also includes a control board and a drive device. The drive device transmits power to the first baffle 32 and controls the rotation of the first baffle 32. A temperature sensor is installed at the gas seat 1 to detect whether gas combustion is taking place at the gas seat 1. The one-way valve, valve assembly 2, temperature sensor, ultraviolet lamp 4, and drive device are all electrically connected to the control board.

[0066] See Figure 5 , Figure 6 , Figures 9-16 Valve assembly 2 includes valve seat 22 and valve core 23.

[0067] The valve seat 22 has a first axis and includes a first U-shaped plate 222, a second U-shaped plate 223, a third U-shaped plate 224, and a fourth U-shaped plate 225. The first U-shaped plate 222, the second U-shaped plate 223, the third U-shaped plate 224, and the fourth U-shaped plate 225 all extend axially along the first axis and are connected sequentially circumferentially along the first axis to form a rotating cavity 221. The connection between the first U-shaped plate 222 and the second U-shaped plate 223 forms a first side ridge 226, the connection between the second U-shaped plate 223 and the third U-shaped plate 224 forms a second side ridge 227, the connection between the third U-shaped plate 224 and the fourth U-shaped plate 225 forms a third side ridge 228, and the connection between the first U-shaped plate 222 and the fourth U-shaped plate 225 forms a fourth side ridge 229. The valve seat 22 is generally a column with a cross-shaped cross-section. The third ozone inlet 21 is located on the third U-shaped plate 224, the first U-shaped plate 222 has a second ozone outlet 24, and the second U-shaped plate 223 has a third ozone outlet 25. The third ozone inlet 21, the third ozone outlet 25, and the second ozone outlet 24 are all connected to the rotating cavity 221. (See also...) Figure 5 and Figure 6 The second ozone outlet 24 is connected to the first ozone inlet 111 via the first gas pipe, and the third ozone outlet 25 is connected to the second ozone inlet 121 via the second gas pipe. The first and second gas pipes can increase the distance between the valve assembly 2 and the gas seat 1, reducing the impact of the high-temperature environment at the gas seat 1 on the effectiveness of the valve assembly 2.

[0068] In this embodiment, the valve core 23 is columnar, and the cross-section of the valve core 23 is fan-shaped. The central angle corresponding to the cross-section of the valve core 23 is greater than 180°. Correspondingly, the valve core 23 is provided with an avoidance notch 231. The valve core 23 is rotatably disposed in the rotating cavity 221 and has a first angle state, a second angle state and a third angle state.

[0069] See Figure 13 and Figure 14When the valve core 23 is in the first angle state, it abuts against the third side edge 228 and the fourth side edge 229. The valve core 23 is spaced apart on the first side edge 226 and the second side edge 227 through the clearance notch 231. Thus, the third ozone inlet 21 is simultaneously connected to the second ozone outlet 24 and the third ozone outlet 25. At this time, the valve seat 22 can simultaneously supply ozone to the first ozone inlet 111 and the second ozone inlet 121. In addition, by rotating the valve core 23 by a small angle in the first angle state, the ventilation space between the second ozone outlet 24 and the third ozone inlet 21, as well as the ventilation space between the third ozone outlet 25 and the third ozone inlet 21, can be changed simultaneously. This causes the ratio of ozone flow rate in the first ozone inlet 111 and the second ozone inlet 121 to change, thereby further adjusting the ratio of flame intensity at the inner flame groove 14 and the outer flame groove 15.

[0070] See Figure 15 When the valve core 23 is in the second angle state, the valve core 23 abuts against the second side edge 227 and the third side edge 228. The valve core 23 is spaced between the first side edge 226 and the fourth side edge 229 through the clearance notch 231. Thus, the valve core 23 not only blocks the ozone flow between the second ozone outlet 24 and the third ozone inlet 21, but also blocks the ozone flow between the third ozone outlet 25 and the third ozone inlet 21. At this time, ozone cannot enter the first ozone inlet 111 and the second ozone inlet 121, and the ratio of the flame size at the inner flame groove 14 and the outer flame groove 15 remains at the normal value.

[0071] See Figure 16 When the valve core 23 is in the third angle state, the valve core 23 abuts against the first side edge 226, the third side edge 228 and the fourth side edge 229. The valve core 23 is spaced apart on the second side edge 227 through the clearance notch 231, thereby connecting the third ozone inlet 21 and the third ozone outlet 25. The valve core 23 blocks the space between the second ozone outlet 24 and the third ozone inlet 21. At this time, only the second ozone inlet 121 can pass ozone in. Therefore, the firepower at the outer flame groove 15 will not change, while the firepower at the inner flame groove 14 will be significantly increased.

[0072] Preferred, see Figures 9-12 The valve assembly 2 also includes a first end cap 26 and a second end cap 27, which are respectively fixed at both ends of the rotating cavity 221 to improve the sealing performance of the rotating cavity 221.

[0073] The first end cap 26 has a first circular hole 261 with the same outer diameter as the valve core 23. The valve core 23 is inserted into the first circular hole 261. Therefore, the valve core 23 can be directly rotated in the rotating cavity 221 by utilizing its fan-shaped cross-section. The end of the valve core 23 is provided with a sealing cap 232, which fits against the first end cap 26 to completely cover the first circular hole 261.

[0074] A support shaft 233 is provided on the inner wall of the valve core 23, and the support shaft 233 passes through the sealing cover 232 and the second end cover 27. The support shaft 233 can increase the connection strength between the sealing cover 232 and the valve core 23, and also make the rotation of the valve core 23 more stable.

[0075] 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.

[0076] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
