[0046] See also Figure 1 and Figure 2 A burner assembly 10 according to an embodiment of the utility model is used for a stove 100. The burner assembly 10 includes a channel member 11, a burner 12, and a fan 13. A first channel 111 and a second channel 112 are provided in the channel member 11, and an air inlet 1111 connected to the first channel 111 is provided in the channel member 11, and the air inlet 1111 is configured to be arranged above the panel 20 of the stove 100. The burner 12 is provided with a third channel 121, and the first channel 111 is connected to the third channel 121 through the second channel 112. The fan 13 is connected to the first channel 111 and the second channel 112, and the fan 13 is configured to be arranged in the body of the stove 100. Among them, the first channel 111, the second channel 112, and the third channel 121 constitute at least a part of the secondary air channel 101 of the burner assembly 10.

[0047] In the burner assembly 10, the fan 13 can inhale secondary air into the first channel 111 through the air inlet 1111 above the stove 100, and send the secondary air to the burner 12 through the fan 13, the second channel 112 and the third channel 121 in sequence, so as to replenish the secondary air for the burner 12. On the one hand, the secondary air inside the fan 13 can absorb the downward radiated heat generated by combustion in the stove 100 body, thereby improving energy efficiency, reducing the temperature rise inside the stove 100 body, and extending the life of the components of the stove 100; on the other hand, by using the air above the panel 20 as the wind source, the problem of difficulty in replenishing secondary air from the inside of the stove 100 body when the cabinet body is relatively closed can be solved.

[0048] Specifically, see Figure 1 and Figure 2 In one embodiment, optionally, the first channel 111 and the second channel 112 are two adjacent annular channels, and the two annular channels are concentrically arranged around the central axis L of the burner 12. The annular channels can realize annular air inlet in the circumferential direction of the burner, which is beneficial to improving the secondary air supplement efficiency.

[0049] The first channel 111 is farther from the central axis L of the burner 12 than the second channel 112. The air inlet 1111 is provided on the side wall of the first channel 111 away from the burner 12, and is used to connect the first channel 111 with the outside air above the panel 20. The fan 13 is provided below the channel member 11, connecting the first channel 111 and the second channel 112.

[0050] The cooker 100 includes a body and a panel 20. The body includes a bottom shell 40. The electrical components of the cooker 100, such as a fan 13 and structural components, can be placed inside the bottom shell 40. An opening is provided above the bottom shell 40. The panel 20 is provided on the bottom shell 40 and covers the opening. The panel 20 is provided with a through hole. The burner assembly 10 passes through the through hole. The channel member 11 is provided on the upper surface of the panel 20. The cooker 100 includes but is not limited to a gas cooker, an integrated cooker, and the like.

[0051] When the burner assembly 10 is working, the fan 13 can suck in the secondary air entering the first channel 111 from the air inlet, and then discharge it into the second channel 112. The secondary air flows from the second channel 112 to the third channel 121, and finally to the fire hole of the burner 12. Thus, the secondary air can be supplemented to the burner assembly 10 through the secondary air channel 101. Optionally, the fan can be a blower.

[0052] The heat generated by the burner 12 when working radiates downward, causing the temperature inside the bottom shell to rise. When the fan 13 is started, on the one hand, secondary air is provided to the burner 12 in the above air intake manner, and on the other hand, when the secondary air passes through the fan 13, the fan 13 can also be cooled, thereby taking away the heat radiated from the burner 12 to the bottom shell, reducing the temperature rise inside the body, and ensuring that the temperature inside the body is within a normal temperature range.

[0053] The utility model does not limit the specific structure of the burner 12. Optionally, the burner 12 can be a single-ring burner, which can form at most one ring of flame when the burner is working. The burner 12 can be a double-ring burner, which can form at most two rings of flame when the burner 12 is working. The burner 12 can be a three-ring burner, which can form at most three rings of flame when the burner 12 is working. The burner 12 can be an infrared burner, which can form an infrared flame when the burner 12 is working. The burner 12 shown in the figure is a double-ring burner and an infrared burner. When the burner 12 is working, it can form at most two rings of flame and an infrared flame, and the infrared flame is located in the middle of the burner 12.

[0088] In this way, the secondary air flowing out of the first air distribution channel 1212 can be evenly distributed to each first fire hole 1231 .

[0089] Specifically, see Figure 1 and Figure 2 The outlet of the first air distribution channel 1212 is in a continuous ring shape, thereby forming an annular gap-shaped air outlet. The outlet of the first air distribution channel 1212 is located obliquely below the first fire hole 1231, which can ensure the flow rate of secondary air flowing out of the first air distribution channel 1212 to fully participate in the combustion of the first fire cover 123.

[0090] See also Figure 1In some embodiments, the first channel portion 141 is substantially parallel to the first surface 1232 .

[0091] In this way, it can be ensured that the secondary air flows out of the first air distribution channel 1212 evenly and smoothly.

[0092] Specifically, see Figure 1 In one embodiment, the first channel portion 141 is substantially parallel to the first surface 1232, and the internal space of the formed first air distribution channel is relatively regular, which can rectify the airflow and make the secondary air flowing out of the first air distribution channel more uniform, thereby ensuring the secondary air replenishment amount of each first fire hole to a certain extent.

[0093] See also Figure 1 and Figure 2 In one embodiment, optionally, an inclination angle between the first channel portion 141 and the first surface 1232 relative to the horizontal direction does not exceed 60 degrees.

[0094] See also Figure 1 and Figure 2 In some embodiments, the second fire cover 124 includes a second surface 1242 facing the first fire cover 123, the second fire hole 1241 penetrates the second surface 1242, the burner assembly 10 includes an air distributor 14, the air distributor 14 includes a second channel portion 142, the second channel portion 142 includes a third enclosure 1422, the third enclosure 1422 extends toward the air distributor plate 122, the second channel portion 142 is connected to the second surface 1242, and at least a portion of the second air distributor channel 1213 is enclosed between the second channel portion 142 and the second surface 1242.

[0095] In this way, the secondary air in the main channel 1211 can be guided to the second fire holes 1241 .

[0096] Specifically, see Figure 1 , Figure 2 and Figure 7 In one embodiment, the cross section of the second channel portion 142 is T-shaped, and its upper surface is parallel to the horizontal plane, and a third enclosure 1422 extends downward. A gap is left between the third enclosure 1422 and the upper surface of the gas distribution plate 122 to prevent interference during installation. The second surface 1242 is perpendicular to the upper surface of the second channel portion 142. After the secondary air flows out of the second channel portion 142, it will flow along the second surface 1242 to the second fire hole 1241, thereby participating in the combustion of the second fire cover 124.

[0097] See also Figure 1 and Figure 2In some embodiments, the second channel portion 142 is provided with a plurality of air supply holes 1421 , which are connected to the second gas distribution channel 1213 , and the plurality of air supply holes 1421 are arranged at intervals along the circumference of the burner 12 , and each air supply hole 1421 corresponds to the portion between two adjacent second fire holes 1241 .

[0098] In this way, the secondary air flowing out from the air supply hole 1421 can be in contact with the fuel gas flowing out from the second fire hole 1241 more fully.

[0099] Specifically, see Figure 1 and Figure 2 In one embodiment, the air supply holes 1421 penetrate the upper surface of the second channel portion 142 and are close to the second surface 1242. Each air supply hole 1421 is disposed below the portion between two adjacent second fire holes 1241, so that the secondary air flowing out of the air supply holes 1421 can be more fully contacted with the gas flowing out of the second fire holes 1241. If the air supply holes 1421 are disposed directly below the second fire holes 1241, the secondary air may blow the gas away, resulting in incomplete combustion.

[0100] See also Figure 1 The flow direction of the secondary air is shown by the dotted line with an arrow in the figure. The secondary air enters the first channel 111 from the air inlet 1111 above the cooker 100, is sucked into the air inlet 131 of the fan 13 from the air inlet 1141, and is discharged from the air outlet 132, enters the second channel 112 from the air outlet 1142, passes through the gap between the second enclosure 1145 and the top plate 1133, enters the main channel 1211 of the third channel 121 from the air outlet 1121, and leads to the first fire hole 1231 and the second fire hole 1241 through the first air distribution channel 1212 and the second air distribution channel 1213, respectively, to replenish the secondary air for the burner 12.

[0101] See also Figure 1 and Figure 2 A stove 100 provided in an embodiment of the utility model includes a panel 20 and a burner assembly 10 of any one of the above embodiments, and the burner assembly 10 is installed on the panel 20 .

[0102] The stove 100 can inhale secondary air into the first channel 111 through the air inlet 1111 above the stove 100 through the fan 13 of the burner assembly 10, and send the secondary air to the burner 12 through the fan 13, the second channel 112 and the third channel 121 in sequence, so as to replenish the secondary air for the burner 12. On the one hand, the secondary air can absorb the downward radiated heat generated by combustion in the stove 100 body inside the fan 13, thereby improving energy efficiency, reducing the temperature rise inside the stove 100 body, and extending the life of the components of the stove 100; on the other hand, by using the air above the panel 20 as the wind source, the problem of difficulty in replenishing secondary air from the body of the stove 100 when the cabinet is relatively closed can be solved.

[0103] Optionally, see Figure 1 and Figure 2 The cooker 100 further includes an energy collecting plate 30, which is disposed on the burner assembly 10, and a bottom case 40 is disposed below the panel 20 and accommodates at least a portion of the burner assembly 10. The energy collecting plate 30 is configured to hold a pot, collect heat energy of the burner assembly 10, and transfer it to the bottom of the pot.
