Detailed Description
In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description illustrates only a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.
The utility model provides a combustor subassembly. The burner assembly may be employed within a cooktop. Therefore, the utility model also provides a cooking utensils, cooking utensils can include any kind of combustor subassembly of the utility model. Cooktops include, but are not limited to, integrated cooktops, conventional gas cooktops, and the like. The burner assembly provided by the present invention can also be applied to other suitable devices, if necessary.
As shown in fig. 1-4, the burner assembly may include a burner 100, a valve body assembly 200, and insulation 300. The burner 100 may have an ejector tube 120. A damper 124 is provided on the nozzle 220 of the valve body assembly 200. The air inlet end 123 of the bleed tube 120 is connected to the damper 124 of the valve body assembly 200. The thermal shield 300 covers at least the valve body assembly 200 and the inlet end 123 of the injection pipe 120 from above. Insulation 300 may be mounted on any suitable component within the cooktop, such as the bottom case (not shown) of the cooktop, a panel glass, and the like. The structure and operation of the burner 100 and the valve body assembly 200 themselves are well known in the art and therefore will not be described in further detail herein.
The nozzle 220 of the valve body assembly 200 is directly inserted into the air inlet of the air inlet end 123 of the injection pipe 120, but the outer diameter of the nozzle 220 is smaller than the inner diameter of the air inlet, and the nozzle 220 is in a suspended state in the air inlet of the injection pipe 120. The valve body assembly 200 is connected to the inlet end 123 of the eductor tube 120 by a damper 124 on the nozzle 220. An air inlet is provided in the damper 124 of the valve body assembly 200 and is aligned with the annular passage between the nozzle 220 and the inlet of the eductor tube 120. The damper 124 may adjust the amount of air introduced into the burner 100 by changing the size of the air inlet through rotation, to adjust the combustion state of the flame. If a backfire occurs in the burner 100 for some reason, flame and heat may be ejected from the air inlets in the damper 124. Therefore, the prior art has provided a baffle just above the damper to provide thermal insulation for the glass panel. However, the inventors have found that the baffle plate has a very limited effect, and that heat emitted from the air inlet port of the damper 124 is emitted in the direction of the emitted heat to the glass panel above the valve body assembly 200, thereby still causing the glass panel to burst.
In contrast, in the burner assembly provided by the present invention, since the heat insulating member 300 covers the air inlet 123 of the injection pipe 120 and the entire valve body assembly 200 from above, when a backfire occurs, the heat can also be blocked by the heat insulating member 300, so that the heat cannot directly impact the glass panel above the valve body assembly 200, thereby effectively protecting the glass panel from being damaged. Moreover, the heat insulation piece 300 can also play a certain role in reflection, and when heat generated by tempering impacts the heat insulation piece 300, the heat insulation piece 300 can reflect a part of heat to a bottom shell of the kitchen range, so that the temperature inside the kitchen range can be reduced, and the quality and the service life of the kitchen range are further improved.
Alternatively, the thermal insulation member 300 may be made of various existing thermal insulation materials; alternatively, the insulation member 300 may be provided on the surface thereof with various kinds of insulation layers existing. Thus, the heat insulation effect of the heat insulation piece 300 is more prominent, and the quality and the service life of the cooker are further improved.
The prior art cookers typically fix the burner 100 and the valve body assembly 200 on the bottom case of the cooker, thereby maintaining the relative positions of the burner 100 and the valve body assembly 200. In order to ensure that the concentricity of the center of the injection pipe 120 of the burner 100 and the nozzle 220 of the valve body assembly 200 is better and ensure the product performance of the cooker, a waist circular hole is arranged on the bottom shell, so that the positions of the burner 100 and the valve body assembly 200 can be adjusted by related personnel conveniently. However, on one hand, due to the structural problem of the waist circular hole, the positions of the furnace end 100 and the valve body assembly 200 are deviated in the transportation process of the stove, so that the furnace end 100 and the nozzle 220 are eccentric, and the performance is affected; on the other hand, the structure needs to be positioned through a tool to enable the furnace end 100 and the valve body assembly 200 to be in butt joint, the requirement on the assembly process of mass production is high, and due to the fact that the positions of the furnace end 100 and the valve body assembly 200 need to be finely adjusted, batch consistency of the cooker is poor, and performance is unstable. Moreover, once the bottom case is deformed during transportation, there is a possibility that an unrecoverable eccentricity between the burner 100 and the nozzle 220 may occur, thereby seriously affecting the performance of the burner assembly.
In view of the above, as shown in fig. 1 to 4, a first end of the heat insulator 300 (the left end of the heat insulator 300 in fig. 1) may be connected to the air inlet end 123 of the injection pipe 120. A second end of insulation 300 (the right end of insulation 300 in fig. 1) may be coupled to valve body assembly 200. The first end and the second end are opposite ends of the thermal insulation member 300, respectively. The first end of the thermal shield 300 may be coupled to the inlet end 123 of the eductor tube 120 by a variety of means, such as welding, adhesives, threading, and the like. Likewise, the second end of the thermal shield 300 may likewise be attached to the valve body assembly 200 in a variety of ways, such as welding, gluing, threading, and the like. The manner in which the first end of the thermal shield 300 is coupled to the inlet end 123 of the eductor tube 120 and the manner in which the second end of the thermal shield 300 is coupled to the valve body assembly 200 may be the same or different.
Like this, heat insulating part 300 can not only play thermal-insulated effect, can also keep the relative position of furnace end 100 and valve body subassembly 200 well, avoids in complete machine assembly and transportation, furnace end 100 and valve body subassembly 200 appear the off-centre scheduling problem, the requirement to assembly process when having reduced cooking utensils volume production for the batch uniformity of cooking utensils is better, the stable performance, and reduced the packaging requirement to the product in the transportation, and the spoilage that the transportation produced the product, therefore can reduce cost effectively. In addition, a firmer fixing structure can be adopted on the bottom shell, so that the position deviation of the furnace end 100 and the valve body assembly 200 in the transportation process is prevented, and the performance of the burner assembly is more stable.
Preferably, as shown in fig. 1 to 4, a top surface of the air inlet end 123 of the injection pipe 120 may be provided with a limiting portion 130 and a first mounting hole 110. The number of the stopper portions 130 and the first mounting holes 110 may be arbitrary.

The number of the position limiting engagement portions 310 may correspond to the number of the position limiting portions 130. The number of the first mounting holes 110 may correspond to the number of the second mounting holes 320. The spacing portion 130 and the spacing mating portion 310 may be engaged. In the embodiment shown in the drawings, the position-limiting portion 130 is a positioning pin, and the position-limiting matching portion 310 is a positioning hole, so that the first end of the heat insulating member 300 is precisely butted against the air inlet end 123 of the injection pipe 120. In an embodiment not shown, the structures of the position-limiting part 130 and the position-limiting matching part 310 can be interchanged, or any other suitable structures can be adopted for the position-limiting part 130 and the position-limiting matching part 310. The first and second mounting holes 110 and 320 may be connected by a first fastener 410. In the embodiment shown in the figures, the first fastener 410 is a threaded connection. In an embodiment not shown, the first fastener 410 may also be a pin or the like. Through the arrangement, the furnace end 100 and the heat insulation piece 300 can be firmly connected together, accurate concentricity between the valve body assembly 200 and the heat insulation piece 300 is ensured, the relative positions of the furnace end 100 and the heat insulation piece 300 are stable, the batch consistency of the cooker is good, and the performance is stable.
Further, as shown in fig. 1 to 4, the ejector pipe 120 may include a high fire ejector pipe 121 and a low fire ejector pipe 122. The large fire ejector tube 121 and the small fire ejector tube 122 are well known in the art and therefore will not be described in further detail herein. The number of the stopper portions 130 may be two. The two limiting portions 130 may be respectively located on top surfaces of air inlet ends of the large fire ejector pipe 121 and the small fire ejector pipe 122. The first mounting hole 110 may be located between the two limiting portions 130. Through the arrangement, the connection stress of the furnace end 100 and the heat insulation piece 300 is uniform, and the connection is firmer.
Preferably, as shown in fig. 1-4, the second end of the thermal insulation member 300 may be provided with a positioning hole 340 and a third installation hole 330. The valve stem 210 of the valve body assembly 200 may pass through the positioning hole 340. The valve body assembly 200 may be provided with a fourth mounting hole 240. The third and fourth mounting holes 330 and 240 may be connected by a second fastener 420. In the embodiment shown in the figures, the second fastener 420 is a threaded connection. In other embodiments not shown, the second fastener 420 may also be a pin or the like. The first fastener 410 and the second fastener 420 may be the same or different. Through the arrangement, the valve body assembly 200 and the heat insulation piece 300 can be firmly connected together, accurate concentricity between the valve body assembly 200 and the heat insulation piece 300 is guaranteed, the relative positions of the valve body assembly 200 and the heat insulation piece 300 are stable, batch consistency of the cooker is good, and the performance is stable. Meanwhile, by passing the valve stem 210 of the valve body assembly 200 through the positioning hole 340, it is ensured that the sealing member in the valve stem 210 is not damaged by high temperature, and the reliability of the valve body assembly 200 is improved.
Further, as shown in fig. 1 to 4, the number of the third mounting holes 330 is two. The two third mounting holes 330 may be respectively located at both sides of the positioning hole 340. Correspondingly, the number of the fourth mounting holes 240 is also two. Through the arrangement, the connection stress of the valve body assembly 200 and the heat insulation piece 300 is uniform, and the connection is firmer.
Preferably, as shown in fig. 1-4, insulation member 300 may include a first plate-like portion 351 and a second plate-like portion 352. The first plate-like portion 351 may be lower than the second plate-like portion 352. The first plate-like portion 351 and the second plate-like portion 352 may be connected by a step 353. A first end of the heat insulator 300 may be disposed on the first plate-shaped portion 351. A second end of insulation member 300 may be disposed on second plate-like portion 352. Through this arrangement, the connection between the burner 100 and the valve body assembly 200 and the heat insulation member 300 can be located in different planes, and can be well attached to the burner 100 and the valve body assembly 200. In addition, when a backfire occurs in the burner 100, the flame and heat emitted from the air inlet of the damper 124 are not only emitted upward to the glass panel but also toward the valve body assembly 200. Lubricating oil is provided in the valve body portion at the top of the valve body assembly 200, which can ensure smooth and stable rotation of the valve rod 210 relative to the valve body portion, and a sealing member is provided in the valve body portion, but once flame and heat generated by tempering are injected to the valve body portion, the lubricating oil is oxidized and fails, the sealing member is damaged, and the valve body assembly 200 is damaged. Because the heat insulation member 300 is well attached to the valve body assembly 200, a gap between the heat insulation member 300 and the valve body assembly 200 is narrow, and the narrow gap can limit the propagation speed of heat under the condition that the heat insulation member 300 has a good heat insulation effect, so that the valve body assembly 200 can be effectively prevented from being damaged.
Further, as shown in FIGS. 1-4, step 353 may be located a greater distance from the first end than the second end. That is, the first plate-like portion 351 has a size larger than that of the second plate-like portion 352 along the axial direction of the nozzle 220. In this way, the heat insulator 300 can be better attached to the valve body assembly 200, and the burner assembly can be more compact in size. Moreover, because the heat insulation member 300 is better attached to the valve body assembly 200, the gap between the heat insulation member 300 and the valve body assembly 200 is narrow, and the narrow gap can limit the propagation speed of heat under the condition that the heat insulation member 300 has a good heat insulation effect, so that the valve body assembly 200 can be more effectively prevented from being damaged.
