[0030] Example 1

[0031] See also Figures 1 to 4As shown, this embodiment provides an energy gathering disk, including an energy gathering disk body and a guide plate 101, the inner annular surface of the energy gathering disk body is provided with a smoke inlet 102, and the outer annular surface of the energy gathering disk body is provided with a smoke outlet 103, and the smoke inlet 102 is connected to the smoke outlet 103; the energy gathering disk body is provided with an inner cavity, and a baffle 104 is provided in the inner cavity, and the baffle 104 is located between the smoke inlet 102 and the smoke outlet 103; the guide plate 101 is fixedly connected to the energy gathering disk body, and the guide plate 101 is located above the smoke inlet 102.

[0032] Based on this structure, the energy gathering disk provided in this embodiment is placed on the periphery of the burner 110 when in use, and the cookware is placed on the energy gathering disk. The high-temperature flue gas generated by the combustion rises, and under the guiding action of the guide plate 101, most of the high-temperature flue gas enters the inner cavity from the flue gas inlet 102, flows along the deflector 104, and is then discharged from the flue gas outlet 103, which is equivalent to extending the time the flue gas stays in the inner cavity, increasing the heat exchange between the high-temperature flue gas and the energy gathering disk, and effectively utilizing the heat conduction of the energy gathering disk to heat the bottom of the cookware, thereby reducing heat loss.

[0033] In this embodiment, see Figure 2 and Figure 3 As shown, the energy-gathering disk body includes an upper disk and a lower disk, the upper disk includes a first annular bottom plate 105 and a first annular side wall 106 extending upward from the outer ring edge of the first annular bottom plate 105, and the upper edge of the first annular side wall 106 is fixedly connected to the lower surface of the guide plate 101; the lower disk includes a second annular bottom plate 107 and a second annular side wall 108 extending upward from the outer ring edge of the second annular bottom plate 107, the upper edge of the second annular side wall 108 is fixedly connected to the lower surface of the guide plate 101, and the inner ring edge of the second annular bottom plate 107 is fixedly connected to the inner ring edge of the first annular bottom plate 105, the upper disk, the lower disk and the guide plate 101 enclose an inner cavity; the smoke inlet 102 is located on the first annular side wall 106, and the smoke outlet 103 is located on the second annular side wall 108.

[0034] Optionally, the upper edge of the first annular side wall 106 is welded to the lower surface of the guide plate 101 , and the upper edge of the second annular side wall 108 is welded to the lower surface of the guide plate 101 .

[0035] Optionally, the second annular bottom plate 107 is in the shape of a hollow cone with openings at both ends, the inner ring diameter of the second annular bottom plate 107 is smaller than the outer ring diameter of the second annular bottom plate 107, the inner ring edge of the second annular bottom plate 107 is bent toward the second annular side wall 108 to form a flange, and the inner ring edge of the first annular bottom plate 105 is welded or abutted against the bending point.

[0036] In this embodiment, the flue gas inlet 102 is located above the flue gas outlet 103, that is, the distance between the flue gas inlet 102 and the guide plate 101 is smaller than the distance between the flue gas outlet 103 and the guide plate 101. This method can ensure that the contact area between the high-temperature flue gas and the upper disk and the lower disk is larger, thereby increasing the heat exchange between the high-temperature flue gas and the energy-gathering disk and reducing heat loss.

[0037] In this embodiment, the guide plate 101 is an annular plate, and the plate surface of the guide plate 101 is perpendicular to the axis of the energy gathering disk. The inner ring diameter of the guide plate 101 is larger than the inner ring diameter of the second annular bottom plate 107.

[0038] Optionally, the inclination angles of the first annular sidewall 106 and the second annular sidewall 108 are substantially the same.

[0039] In this embodiment, the baffle 104 is a tubular structure, and the axis of the baffle 104 coincides with the axis of the energy collecting disk body; Figure 2 As shown, the diameter of the tubular structure gradually decreases from the end of the tubular structure close to the guide plate 101 to the end of the tubular structure away from the guide plate 101.

[0040] In a possible design, one end of the baffle 104 is fixedly connected to the lower surface of the guide plate 101, and a gap is set between the other end of the baffle 104 and the upper surface of the bottom plate of the energy collecting disk body.

[0041] Optionally, one end of the baffle 104 is welded to the lower surface of the guide plate 101, and a gap is set between the other end of the baffle 104 and the upper surface of the second annular bottom plate 107 to ensure that the high-temperature flue gas entering the inner cavity from the flue gas inlet 102 can flow through the gap and then be discharged from the flue gas outlet 103, thereby extending the residence time of the high-temperature flue gas in the inner cavity, making the heat exchange between the high-temperature flue gas and the energy collecting disk more sufficient, and reducing heat loss.

[0042] In another possible design, one end of the baffle 104 is fixedly connected to the bottom plate of the energy gathering disk body, and a gap is set between the other end of the baffle 104 and the lower surface of the guide plate 101.

[0043] Optionally, one end of the baffle 104 is welded to the upper surface of the second annular bottom plate 107, and a gap is set between the other end of the baffle 104 and the lower surface of the guide plate 101. At this time, the center line of the flue gas inlet 102 can be located below the end face of the other end of the baffle 104 to avoid heat loss caused by the high-temperature flue gas entering the inner cavity from the flue gas inlet 102 being directly discharged from the gap.

[0044] Furthermore, there are multiple baffles 104, and the multiple baffles 104 are spaced apart along the radial direction of the energy collecting disk body. Among two adjacent baffles 104, one baffle 104 is fixedly connected to the lower surface of the guide plate 101, and the other baffle 104 is fixedly connected to the upper surface of the second annular bottom plate 107.

[0045] In this embodiment, there are two baffles 104. The upper end of the baffle 104 close to the first annular side wall 106 is welded to the lower surface of the guide plate 101, and a gap is set between the lower end and the upper surface of the second annular bottom plate 107; the lower end of the baffle 104 away from the first annular side wall 106 is welded to the upper surface of the second annular bottom plate 107, and a gap is set between the upper end and the lower surface of the guide plate 101. Figure 3 As shown, Figure 3 The direction of the middle arrow indicates the flow direction of the high-temperature flue gas. The two baffles 104 divide the inner cavity into three heat exchange channels. After the high-temperature flue gas enters from the flue gas inlet 102, it flows through the three heat exchange channels in sequence and is discharged from the flue gas outlet 103.

[0046] Furthermore, the energy gathering disk further includes an annular baffle 109 , the inner edge of which is fixedly connected to the outer annular surface of the energy gathering disk body, and the annular baffle 109 is located below the smoke outlet 103 .

[0047] In this embodiment, the inner ring edge of the annular baffle 109 is welded to the outer surface of the second annular side wall 108 .

[0048] The flue gas discharged from flue gas outlet 103 further heats annular baffle 109, reducing heat losses from flue gas exchange with external cold air. The heat conduction from annular baffle 109 preheats the secondary air at the bottom of the lower tray, fully utilizing the heat from the high-temperature flue gas to further improve thermal efficiency. At the same time, annular baffle 109 blocks the downward movement of flue gas from flue gas outlet 103, reducing the impact of flue gas on the replenishment of secondary air, ensuring smooth replenishment of secondary air, and improving the stability of burner 110.

[0049] Furthermore, there are multiple smoke inlets 102, which are evenly spaced along the inner annular surface of the energy concentrating disk body; there are multiple smoke outlets 103, which are evenly spaced along the outer annular surface of the energy concentrating disk body.

[0050] The energy-gathering plate provided in this embodiment also includes a first leg 111 and a second leg 112. The first leg 111 is welded to the lower plate and is used to mount the energy-gathering plate on the periphery of the burner 110; the second leg 112 is welded to the guide plate 101 and is used to support the cookware.

[0051] This embodiment also provides a cooker, including the energy-gathering plate provided in this embodiment.

[0052] The stove provided in this embodiment uses the energy-gathering plate provided in this embodiment, which can increase the heat exchange between high-temperature flue gas and the energy-gathering plate, effectively utilize the heat conduction of the energy-gathering plate to heat the bottom of the pot, reduce heat loss, and improve the thermal efficiency of the stove.

[0053] Further, see Figure 4 As shown, the cooker further includes a burner 110 , and a gap is provided between the circumferential surface of the burner 110 and the inner annular surface of the energy concentrating disk body.

[0054] Figure 4 In the figure, the direction of the solid arrow indicates the flow direction of the high-temperature flue gas, and the direction of the dotted arrow indicates the flow direction of the secondary air. The secondary air enters from the gap between the circumferential surface of the burner 110 and the inner annular surface of the energy-gathering disk body and mixes with the fuel gas to improve thermal efficiency.

[0055] Example 2

[0056] See also Figures 5 to 7 As shown, this embodiment also provides an energy-gathering disk. The energy-gathering disk of this embodiment is an improvement on the first embodiment. The technical solutions of the first embodiment also belong to this embodiment and will not be described again here. The same reference numerals as in the first embodiment are used for the same components, and reference is made to the description of the first embodiment here.

[0057] In this embodiment, the baffle 104 is an annular plate structure, and the axis of the baffle 104 coincides with the axis of the energy collecting disk body; the annular inner edge of the baffle 104 is fixedly connected to the inner annular surface of the energy collecting disk body, and a gap is set between the annular outer edge of the baffle 104 and the outer annular surface of the energy collecting disk body, or the annular inner edge of the baffle 104 is fixedly connected to the outer annular surface of the energy collecting disk body, and a gap is set between the annular outer edge of the baffle 104 and the inner annular surface of the energy collecting disk body.

[0058] Optionally, the plate surface of the deflector 104 is perpendicular to the axis of the energy concentrating disk body.

[0059] In one possible design, the annular inner edge of the baffle 104 is welded to the first annular side wall 106, and a gap is set between the annular outer edge of the baffle 104 and the inner surface of the second annular side wall 108, so that the high-temperature flue gas entering the inner cavity from the flue gas inlet 102 can flow through the gap and then be discharged from the flue gas outlet 103, thereby extending the residence time of the high-temperature flue gas in the inner cavity, making the heat exchange between the high-temperature flue gas and the energy collecting disk more complete, and reducing heat loss.

[0060] In another possible design, the annular inner side edge of the baffle 104 is welded to the second annular side wall 108 , and a gap is set between the annular outer side edge of the baffle 104 and the inner surface of the first annular side wall 106 .

[0061] Furthermore, there are multiple baffles 104, and the multiple baffles 104 are spaced apart along the axial direction of the energy collecting disk body. Among two adjacent baffles 104, the annular inner edge of one baffle 104 is fixedly connected to the inner annular surface of the energy collecting disk body, and the annular inner edge of the other baffle 104 is fixedly connected to the outer annular surface of the energy collecting disk body.

[0062] In this embodiment, there are three baffles 104. The baffles 104 near the smoke inlet 102 and the baffles 104 away from the smoke inlet 102 have their annular inner edges welded to the first annular sidewall 106, with gaps being provided between their annular outer edges and the inner surface of the second annular sidewall 108. The baffle 104 located in the middle has its annular outer edge welded to the second annular sidewall 108, with a gap being provided between its annular inner edge and the inner surface of the first annular sidewall 106.

[0063] See also Figure 6 As shown, Figure 6 The direction of the middle arrow indicates the flow direction of the high-temperature flue gas. The three deflectors 104 divide the inner cavity into four heat exchange channels. After the high-temperature flue gas enters from the flue gas inlet 102, it flows through the three upper heat exchange channels in sequence. Most of the flue gas is discharged from the flue gas outlet 103. A small amount of flue gas exists in the heat exchange channel at the bottom of the lower plate and will eventually be discharged from the flue gas outlet 103.

[0064] This embodiment also provides a cooker, including the energy-gathering plate provided in this embodiment.

[0065] The stove provided in this embodiment uses the energy-gathering plate provided in this embodiment, which can increase the heat exchange between high-temperature flue gas and the energy-gathering plate, effectively utilize the heat conduction of the energy-gathering plate to heat the bottom of the pot, reduce heat loss, and improve the thermal efficiency of the stove.

[0066] Further, see Figure 7 As shown, the cooker further includes a burner 110 , and a gap is provided between the circumferential surface of the burner 110 and the inner annular surface of the energy concentrating disk body.

[0067] Figure 7 In the figure, the direction of the solid arrow indicates the flow direction of the high-temperature flue gas, and the direction of the dotted arrow indicates the flow direction of the secondary air. The secondary air enters from the gap between the circumferential surface of the burner 110 and the inner annular surface of the energy-gathering disk body and mixes with the fuel gas to improve thermal efficiency.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
