The first aspect of the present application discloses an upper burner 2000 and the second aspect of the present application discloses an oven 1000.

The toaster 1000 is a household appliance for toasting food materials using heat in a relatively closed space, and generally, the toaster includes a gas-type toaster using combustion of gas as a heat source and an electric-type toaster using electric heating of a heating tube as a heat source, and the upper burner 2000 will be described in detail herein with respect to the gas-type toaster (hereinafter referred to as the toaster 1000).

As shown in fig. 3 and 4, the oven 1000 has a first chamber 1100 and a second chamber 1200, the first chamber 1100 occupies a certain volume in space, thereby enclosing a receiving cavity 1110, forming a hollow structure, the receiving cavity 1110 is used for placing a grill 1300, the grill 1300 can be pushed into and pulled out of the receiving cavity 1110 by a user, food is placed on the grill 1300, and baking of the food is achieved in the receiving cavity 1110 by using high temperature. The front of the receiving cavity 1110 forms an opening 1111 through which the grill 1300 enters and exits the receiving cavity 1110, and the toaster 1000 has a door 1400, the door 1400 closing and opening the opening 1111.

The first chamber 1100 is provided with an upper burner 2000 and a lower burner 3000, the upper burner 2000 is in a plate shape with a flat structure, and is arranged at the top of the first chamber 1100 to realize top-down baking and heating of food materials, and the lower burner 3000 is in a tube shape, and is arranged at the bottom of the first chamber 1100 to realize bottom-up baking and heating of food materials. The upper burner 2000 and the lower burner 3000 comprise an air inlet cavity and a fire outlet hole, and the fuel gas is introduced into the air inlet cavity 2280 and then sprayed out from the fire outlet hole 2270 to be ignited to form a flame, so that the high temperature is formed to realize the baking of the food. Generally, the lower burner 3000 includes two lower burners 3000, which are respectively located at the left side and the right side of the accommodating cavity 1110, and the lower burner 3000 located at the left side is used for baking food from bottom to top and from left to right, and the lower burner 3000 located at the right side is used for baking food from bottom to top and from right to left.

In the process of baking food materials, smoke is generated in the accommodating cavity 1110, the smoke needs to be discharged in time, specifically, the second cavity 1200 also forms a hollow structure and encloses the exhaust flue 1210, the accommodating cavity 1110 is communicated with the exhaust flue 1210, and the smoke can be discharged into the exhaust flue 1210 and then discharged through the exhaust flue 1210.

As shown in fig. 5, 6, 10 and 11, the upper burner 2000 includes a top plate 2100 and a bottom plate 2200, the bottom plate 2200 is positioned under the top plate 2100, and the top plate 2100 and the bottom plate 2200 are overlapped with each other to be coupled together such that an air intake chamber 2280 is formed between the top plate 2100 and the bottom plate 2200, the bottom plate 2200 is provided with a fire outlet 2270, and when the upper burner 2000 is mounted to a predetermined position of the oven 1000, i.e., the top of the first chamber 1100, the bottom plate 2200 faces toward the accommodating chamber 1110, and the top plate 2100 faces away from the accommodating chamber 1110, so that the fire outlet 2270 opened on the bottom plate 2200 is opened toward the accommodating chamber 1110, and a flame is generated toward the accommodating chamber 1110 when fuel gas is ejected from the fire outlet 2270.

Since the upper burner 2000 is installed on the top of the first chamber 1100 just above the grill 1300, in order to allow a wide range of coverage when the upper burner 2000 burns, a plurality of combustion areas are provided on the base plate 2200, and the plurality of combustion areas are arranged correspondingly, so that a wide range of coverage can be achieved. It should be understood that the combustion zone is a zone where a flame can be generated, and the flame is formed by spraying fuel gas from the flame outlet 2270 and igniting the fuel gas, that is, the combustion zone is formed by arranging a plurality of flame outlet 2270.

Referring to fig. 7, in this embodiment, the multiple combustion areas respectively include a third combustion area 2250, a second combustion area 2240, and a first combustion area 2230, and the combustion of the upper burner 2000 needs to be implemented by matching with the ignition of an ignition needle, specifically, the ignition needle needs to be disposed near the fire hole 2270, and the tip of the ignition needle discharges to form an electric spark, so as to ignite the fuel gas.

For the third combustion zone 2250, the second combustion zone 2240 and the first combustion zone 2230, in order to avoid increasing the number of ignition needles, the third combustion zone 2250, the second combustion zone 2240 and the first combustion zone 2230 are arranged to intersect, specifically, the end of the third combustion zone 2250, the end of the second combustion zone 2240 and the end of the first combustion zone 2230 are intersected, so-called intersection is understood to be intersection, so that only one ignition needle may be arranged to ignite any one of the third combustion zone 2250, the second combustion zone 2240 and the first combustion zone 2230, i.e., fire may be transferred to the other two.

Specifically, as shown in fig. 8, the third combustion region 2250, the second combustion region 2240 and the first combustion region 2230 are respectively provided with an intersection section (2231/2241/2251), the so-called intersection section (2231/2241/2251) is a region of a certain length along the extending direction of each combustion region (2230/2240/2250), and the third combustion region 2250, the second combustion region 2240 and the first combustion region 2230 intersect each other through the respective intersection sections (2231/2241/2251) to form an intersection 2260, that is, the intersection sections (2231/2241/2251) constitute the end portions of each combustion region.

When the third combustion area 2250, the second combustion area 2240 and the first combustion area 2230 meet, the second combustion area 2240 and the first combustion area 2230 form a U shape, and the third combustion area 2250 is located between the second combustion area 2240 and the first combustion area 2230, that is, the three combustion areas form a "mountain" structure, which is not only beneficial to flame transfer, but also is open between the other ends of the third combustion area 2250, the second combustion area 2240 and the first combustion area 2230, which is beneficial to smoke discharge and avoids smoke aggregation.

For example, as shown in connection with fig. 4, 6 and 7, when the upper burner 2000 is mounted to the oven 1000, the smoke generated in the receiving cavity 1110 is discharged from the front to the rear by relaying the flow of the smoke from the receiving cavity 1110 into the smoke discharging duct 1210, with the opening 1111 of the receiving cavity 1110 being the front and the orientation of the smoke discharging duct 1210 being the rear. The third combustion zone 2250, the second combustion zone 2240 and the first combustion zone 2230 meet at the front and extend toward the rear, and are open to each other at the rear, so that the flames generated from the third combustion zone 2250, the second combustion zone 2240 and the first combustion zone 2230 form a flame wall, and the smoke between the first combustion zone 2230 and the third combustion zone 2250 and between the second combustion zone 2240 and the third combustion zone 2250 can be smoothly discharged by being open at the rear.

The third combustion area 2250, the first combustion area 2230 and the second combustion area 2240 are designed to be intersected with each other, the intersection 2260 is located relatively at a middle position, the intersection 2260 can form local high temperature, the uniform distribution of temperature has larger influence, in order to avoid the intersection 2260 forming local temperature aggregation, the fire outlet area of the intersection 2260 is reduced, the fire outlet area is reduced, the flame is reduced, the temperature is reduced, and the local high temperature of the intersection 2260 can be reduced, so that the uniform distribution of the temperature of the accommodating cavity 1110 is more facilitated, and the baking effect on food materials is ensured.

Specifically, the reduction of the fire area of junction 2260 may be achieved by reducing the fire area of the junction (2231/2241/2251) of at least one of third combustion zone 2250, second combustion zone 2240, and first combustion zone 2230.

For example, a first adjacent section (2232/2242/2252) is defined on the third combustion zone 2250, the second combustion zone 2240 and the first combustion zone 2230, respectively, the first adjacent section (2232/2242/2252) being of equal length and adjacent to the junction section (2231/2241/2251). It is understood that the length of the sections 2231 in the first combustion zone 2230 is L, the length of the adjacent sections 2232 in the first combustion zone 2230 is L, and the length of the sections 2241 in the first and second combustion zones 2232, 2240 may be different from each other based on the extending direction of the same combustion zone, as shown in fig. 8.

By designing the fire exit area of the junction of at least one of the third combustion zone 2250, the second combustion zone 2240, and the first combustion zone 2230 to be smaller than the fire exit area of the first adjacent section of the one, the fire exit area of the junction 2260 can be made smaller, thereby reducing the local high temperature of the junction 2260.

It is possible to design only the fire exit area of the intersection section 2231 of the first combustion zone 2230 to be smaller than the fire exit area of the first adjacent section 2232 of the first combustion zone 2230, or to design only the fire exit area of the intersection section 2241 of the second combustion zone 2240 to be smaller than the fire exit area of the first adjacent section 2242 of the second combustion zone 2240, or to design only the fire exit area of the intersection section 2251 of the third combustion zone 2250 to be smaller than the fire exit area of the first adjacent section 2252 of the third combustion zone 2250.

It is also possible to design the fire exit area of the intersection section 2231 of the first combustion zone 2230 smaller than the fire exit area of the first adjacent section 2232 of the first combustion zone 2230, and design the fire exit area of the intersection section 2241 of the second combustion zone 2240 smaller than the fire exit area of the first adjacent section 2242 of the second combustion zone 2240; or the fire-out area of the intersection section 2231 of the first combustion zone 2230 is designed to be smaller than the fire-out area of the first adjacent section 2232 of the first combustion zone 2230, and the fire-out area of the intersection section 2251 of the third combustion zone 2250 is designed to be smaller than the fire-out area of the first adjacent section 2252 of the third combustion zone 2250; or the area of the fire out of the intersection 2241 of the second combustion zone 2240 is designed to be smaller than the area of the fire out of the first adjacent section 2242 of the second combustion zone 2240, and the area of the fire out of the intersection 2251 of the third combustion zone 2250 is designed to be smaller than the area of the fire out of the first adjacent section 2252 of the third combustion zone 2250.

It is also possible to design the fire exit area of the intersection section 2231 of the first combustion zone 2230 smaller than the fire exit area of the first adjacent section 2232 of the first combustion zone 2230, design the fire exit area of the intersection section 2241 of the second combustion zone 2240 smaller than the fire exit area of the first adjacent section 2242 of the second combustion zone 2240, and design the fire exit area of the intersection section 2251 of the third combustion zone 2250 smaller than the fire exit area of the first adjacent section 2252 of the third combustion zone 2250.

The above solutions can reduce the area of the fire at the junction 2260 of the third combustion zone 2250, the second combustion zone 2240 and the first combustion zone 2230, thereby reducing the local high temperature at the junction 2260.

It will be appreciated that the fire exit area is defined by the fire exit holes 2270, and that the reduction in the fire exit area may be accomplished by the number or density of the fire exit holes 2270, etc.

For example, the first combustion zone 2230 is illustrated, and the second combustion zone 2240 and the third combustion zone 2250 have similar technical effects, and thus, the description thereof will not be repeated. As shown in connection with fig. 8, the number of fire holes 2270 at the end of the first combustion zone 2230 (junction section 2231) is less than the number of fire holes 2270 of the first adjacent section 2232 of the first combustion zone 2230. When the number of the fire holes 2270 at the end (the junction 2231) of the first combustion zone 2230 becomes smaller, the fire area becomes smaller accordingly, and the intensity of the flame formed becomes smaller accordingly, so that the temperature of the junction 2260 can be lowered. In addition to the variation in the number of the fire holes 2270, the density of the fire holes 2270 at the end (the junction 2231) of the first combustion zone 2230 may be smaller than the density of the fire holes 2270 at the first adjacent segment of the first combustion zone 2230, and when the density of the fire holes 2270 is reduced, the area per unit area of the fire is reduced, so that the local temperature at the junction 2260 can be reduced.

Alternatively, in general, the receiving cavity 1110 is substantially rectangular, and in order to allow the upper burner 2000 to have a large area of coverage, the whole of the combustion zone (2230/2240/2250) on the bottom plate 2200 is also substantially designed to be rectangular matching the receiving cavity 1110, so that the space is more effectively utilized and uniform baking of the food material is achieved.

As shown in connection with fig. 7, in some embodiments of the present application, the second combustion zone 2240 includes a longitudinal partition 2244 and a transverse partition 2243, the first combustion zone 2230 also includes a longitudinal partition 2234 and a transverse partition 2233, and the transverse partition 2243 of the second combustion zone 2240 and the transverse partition 2233 of the first combustion zone 2230 extend in the left-right direction to meet together, it being understood that the above-mentioned meeting section (2231/2241) and the first adjacent section (2232/2242) may be formed by the transverse partition (2233/2243).

The end of the third combustion zone 2250 (intersection 2251) intersects the lateral section 2243 of the second combustion zone 2240 and the lateral section 2233 of the first combustion zone 2230. The junction 2260 of the third combustion zone 2250, the second combustion zone 2240 and the first combustion zone 2230 is located at the front with respect to the overall arrangement of the three, the longitudinal sections 2234 of the first combustion zone 2230 and the longitudinal sections 2244 of the second combustion zone 2240 extending in the front-rear direction, so that the longitudinal sections (2234/2244) and the transverse sections (2233/2243) form corners, which better adapt to the space of the receiving cavity 1110.

As shown in connection with fig. 7 and 9, in some embodiments of the present application, in order to facilitate the ignition of the upper burner 2000, an ignition section 2235 is provided on any one of the longitudinal sections (2234/2244), and the ignition area of the ignition section 2235 is set to be larger, so that it is easier to be ignited by the ignition needle and then to transfer the fire to the entire upper burner 2000, and to ensure the normal induction of the induction needle and then to maintain the combustion state of the upper burner 2000.

Specifically, taking the case of setting the ignition section 2235 on the longitudinal partition 2234 of the first combustion zone 2230 as an example, defining a second adjacent section 2236 on the longitudinal partition 2234, where the second adjacent section 2236 is adjacent to the ignition section 2235 and has the same length, it can be considered that the rest of the longitudinal partition 2234 except for the ignition section 2235 is formed by a plurality of second adjacent sections 2236, so that the ignition section 2235 forms the part with the largest fire area, and the fire area is larger, so that the quantity of the injected fuel gas is larger, the ignition needle is set near the ignition section 2235, and the electric spark generated by the ignition needle ignites the fuel gas injected from the ignition section 2235 more easily, and then transfers the fuel gas to other areas, thereby realizing the combustion of the whole upper burner 2000. It will be appreciated that the upper burner 2000 needs to be continuously fired by a sensing needle which senses a flame to generate a signal to ensure the valve is opened to enable the combustion gas to be continuously fed into the upper burner 2000, and the ignition section 2235 is provided with a larger flame outlet area to enable the sensing needle to be surrounded by the flame to ensure normal operation. It is to be appreciated that ignition segment 2235 can also be disposed in longitudinal section 2244 of second combustion zone 2240.

Since the first combustion zone 2230 and the second combustion zone 2240 are closer to both sides of the upper burner 2000 than the third combustion zone 2250, the arrangement of the ignition section 2235 on the longitudinal partition 2234 can prevent the ignition needle and the sensing needle from excessively extending into the receiving cavity 1110 to occupy the space of the receiving cavity 1110. In addition, when the third combustion zone 2250, the second combustion zone 2240 and the first combustion zone 2230 meet at the front, the ignition section 2235 is located at a relatively rear position, thus preventing the ignition needle and the sensing needle from being easily observed by the user, improving the safety in use.

Alternatively, as shown in connection with fig. 9, in some embodiments of the present application, two ignition segments 2235 are included, and two ignition segments 2235 are disposed at intervals, because two ignition segments 2235 are disposed at intervals, one of the ignition segments 2235 can cooperate with a sensing pin, and the other ignition segment 2235 can cooperate with a sensing pin, which is spaced apart from the sensing pin, so that the mounting of the sensing pin and the sensing pin is easier.

It will be appreciated that the fire exit area of the fire section 2235 may be adjusted by the density or number of fire exit holes 2270. For example, as shown in connection with fig. 9, the density of the fire holes 2270 of the fire section 2235 is greater than the density of the fire holes 2270 of the second adjacent section 2236, and as the density of the fire holes 2270 is greater, the fire exit area per unit area is also greater, which may also more effectively match the sensing pin and/or the ignition pin. It is also possible that the number of fire holes 2270 of the ignition segment 2235 is greater than the number of fire holes 2270 of the second adjacent segment 2236, and when the number of fire holes 2270 of the ignition segment 2235 is greater, the fire area is correspondingly greater, and the resulting flame intensity is correspondingly greater, so that the sensing pin and/or the ignition pin can be more effectively matched.

As shown in conjunction with fig. 6, 7, and 11, in some embodiments of the present application, the base plate 2200 is provided with a second region 2220 and a first region 2210, one of the second region 2220 and the first region 2210 is higher than the other of the second region 2220 and the first region 2210, and a third combustion region 2250, a second combustion region 2240, and a first combustion region 2230 are provided at the first region 2210. By the height arrangement of the second area 2220 and the first area 2210, the base plate 2200 is formed in a concave-convex structure, so that the structural strength of the base plate 2200 can be enhanced, and the base plate 2200 is prevented from vibrating during the operation of the upper burner 2000.

During the baking process, smoke is generated in the accommodating cavity 1110, and the smoke needs to be discharged out of the accommodating cavity 1110, so that the oven 1000 has a smoke discharge duct 1210, the smoke discharge duct 1210 is communicated with the accommodating cavity 1110, and the smoke can be discharged out of the accommodating cavity 1110 through the smoke discharge duct 1210. Because the flue gas has a higher temperature, the flue gas floats upwards and is easy to gather near the lower burner 3000 (near the lower space of the lower burner 3000), and the gathering of the flue gas can cause the flame of each combustion zone (2230/2240/2250) to fly, so that the combustion performance is reduced, and the baking effect on the food materials is affected. For this reason, as shown in fig. 11, the first area 2210 is designed to be lower than the second area 2220, that is, the first area 2210 is designed to be lower in the up-down direction, so that the smoke can be prevented from drifting the flames of the respective combustion areas (2230/2240/2250).

Specifically, the base plate 2200 is formed in two regions, namely, the second region 2220 and the first region 2210, and by designing the second region 2220 and the first region 2210 to be not equally high, the second region 2220 is positioned at a higher position, and the third combustion region 2250, the second combustion region 2240 and the first combustion region 2230 are positioned at a lower first region 2210, and in the height direction (up-down direction), the second region 2220 forms a certain space from the first region 2210, and smoke enters the aforementioned space while floating upward, thereby avoiding a long stay in the vicinity of the first region 2210 (near the lower space of the first region 2210), thereby reducing the influence on flames, preventing flame drift, ensuring combustion performance, and thus ensuring the baking effect on food materials.

Specifically, the bottom plate 2200 is a sheet metal member having high ductility, and the first region 2210 and the second region 2220 can be formed by press forming, and since the second region 2220 is located at a higher position, the first region 2210 protrudes downward, and a certain space is formed between the second region 2220 and the first region 2210 in the up-down direction. When the flue gas in the accommodating cavity 1110 floats upwards, the flue gas will continue to flow upwards after encountering the first area 2210 and enter the space formed by the second area 2220 relative to the first area 2210, and then is discharged into the exhaust flue 1210, because the first area 2210 is at a lower position, and the flue gas will continue to float towards a higher position after encountering the barrier of the first area 2210. It may be that the space formed by the second area 2220 from the first area 2210 is directly connected to the exhaust duct 1210, so that the flue gas floats upward into the space and then directly enters the exhaust duct 1210. The space formed by the second area 2220 from the first area 2210 may not be directly connected to the exhaust duct 1210, so that the smoke needs to flow along with the whole smoke discharging direction after floating upwards into the space, and then the smoke enters the exhaust duct 1210, although the space formed by the second area 2220 from the first area 2210 in this case is not directly connected to the exhaust duct 1210, the smoke can be prevented from interfering with all the fire holes 2270 when flowing along with the smoke discharging direction. By designing the second area 2220 and the first area 2210 to be not equal in height, not only the structural strength of the base plate 2200 is enhanced, but also the interference of smoke to flames can be avoided, thereby ensuring the baking effect.

Alternatively, in order to match the distribution of the third combustion zone 2250, the second combustion zone 2240 and the third combustion zone 2250, the second areas 2220 include two second areas 2220, and the two second areas 2220 are arranged side by side at a certain distance, so that the two second areas 2220 are respectively surrounded by the first areas 2210, so that the first areas 2210 form an "8" -shaped structure, and thus, the combustion zones are more easily arranged. As shown in fig. 7, since the third combustion zone 2250, the second combustion zone 2240, and the third combustion zone 2250 are disposed in the first region 2210, one of the second regions 2220 corresponds between the third combustion zone 2250 and the first combustion zone 2230, and the other of the second regions 2220 corresponds between the third combustion zone 2250 and the second combustion zone 2240, a wide coverage of each combustion zone is achieved while enhancing the structural strength of the base plate 2200.

As described above, the accommodating cavity 1110 has the opening 1111, as shown in fig. 4 and 7, the opening 1111 is located in front of the accommodating cavity 1110, and is closer to the user, so that the user can conveniently take and put food through the opening 1111, and the exhaust flue 1210 is located behind the accommodating cavity 1110, so as to avoid the influence of the exhaust of smoke on the user. When both the second combustion zone 2240 and the first combustion zone 2230 include longitudinal sections (2234/2244) and transverse sections (2233/2243), the transverse sections 2243 of the second combustion zone 2240, the transverse sections 2233 of the first combustion zone 2230, and the third combustion zone 2250 meet in an orientation adjacent to the opening 1111, the longitudinal sections 2244 of the second combustion zone 2240, the longitudinal sections 2234 of the first combustion zone 2230, and the third combustion zone 2250 extend rearward and open rearward with respect to each other, and it is the open rearward arrangement of the respective combustion zones that provides a passageway for the flow of flue gas, such that, as the flue gas enters the space formed by the second zone 2220 from the first zone 2210, the flue gas may flow rearward of the respective combustion zones as a whole, avoiding obstruction to the flow of the flue gas.

Alternatively, as shown in connection with fig. 6 and 7, in some embodiments of the present application, the second combustion zone 2240 and the first combustion zone 2230 extend rearward to a greater extent than the third combustion zone 2250, thus facilitating the evacuation of flue gas into the corresponding space of the second zone 2220. Specifically, the longitudinal sections 2244 of the second combustion zone 2240 and the longitudinal sections 2234 of the first combustion zone 2230 extend rearward and over the second zone 2220, while the third combustion zone 2250 extends only at a location where the first zone 2210 is located between the two second zones 2220, e.g., at a location defining the first zone 2210 as an intermediate location 2211 between the two second zones 2220, at a location defining the first zone 2210 rearward of the two second zones 2220 as a rearward location 2212 (i.e., at a location where the first zone 2210 is further rearward than the two second zones 2220), the first combustion zone 2230 and the second combustion zone 2240 extend to the rearward location 2212 (i.e., at a location where a portion of the first combustion zone 2230 and a distribution of the second combustion zone 2240 are located rearward of the second location), the third combustion zone 2250 extends at the intermediate location 2211 (i.e., not located rearward of the second location 2212), the length of extension of the third combustion zone 2250 is at least 2/3 of the length of the intermediate 2211, e.g., the length of the third combustion zone 2210 as the length of the entire length of the intermediate zone 2211 can be equal to the length of the intermediate zone 2251 in the direction (e.g., the entire length of the third combustion zone 2250 can be equal to the length of the intermediate location 2251 in the depth of the intermediate zone 2254). In addition, since the third combustion area 2250 is only disposed at the middle portion 2211 and does not extend to the rear portion 2212, when the smoke flows backward beyond the third combustion area 2250, the two smoke flows can meet each other (two smoke flows respectively correspond to the smoke flowing out of the space below the two second areas 2220), so that the space where the smoke flows out is increased, the flowing-out of the smoke is quickened, the influence on the flame is avoided, and since the rear portion 2212 is located at a position relatively far backward from the accommodating cavity 1110, the corresponding accommodating cavity 1110 space is provided for most of the smoke to flow through, so that the second combustion area 2240 is prevented from extending to the rear portion 2212 to form scorching of food materials at the position relatively backward from the accommodating cavity 1110.
