Description

Gas stove combined structure

The invention relates to a bonding structure, in particular to a gas stove coupling structure.

Gas stoves have become an indispensable item in daily life, and most of the usual gas stoves are placed in the kitchen of the home, which is of great help to the efficiency of cooking. However, although the conventional gas stove has the advantages of improving the efficiency of cooking ingredients, there are still the following drawbacks in terms of use and structure:

First, as shown in FIG. 1 and FIG. 2, the conventional gas stove seat 1 comprises: a set of furnace bottom chassis 2 placed in a mixing tube 5, and a furnace top connected to the furnace base 2 The disc 3, due to the combination of the furnace base 2 of the conventional gas stove 1 and the top plate 3 of the furnace, not only causes the mold cost and production cost of the manufacturer, but also is very time consuming in subsequent processing and assembly. Since the contact area of the stove base 2 and the top plate 3 of the hob is very limited, even if the joint precision is not well combined, a slight gap is left, which may be loose due to the difference in strength after the combination. Or the problem of damage, once the furnace base 2 and the top plate 3 of the furnace are not properly loosened, the most serious is that the mixing tube 5 is supplied with gas during the cooking of the ingredients, due to the overall stability Destruction, resulting in irreparable results, even if it is not a very serious degree, will also make users nervous all day long. In addition, as can be seen from the above, the furnace seat pan 2 and the hob top plate 3 need to be processed in the subsequent steps to obtain a complete gas stove seat 1 finished product, and the conventional processing operations are quite inconvenient, and The working hours have also been lengthened, adding a lot of costs to the invisible, which does not meet the economic principles.

Secondly, when the conventional gas stove seat 1 and the outer ring furnace cover 4 are used for a period of time, the gas stove seat 1 and the outer ring furnace cover 4 are often worn out due to the use thereof during assembly and disassembly and cleaning. The cover is closed, and the user simply chooses to wipe the surface with a rag, but does not clean the grease stains stored in the inner layer. Although the appearance looks very bright after a while, the interior is long because of the long time. Corrosion causes various problems, resulting in the formation of a gap at the position where the gas furnace seat 1 and the outer ring furnace cover 4 are closed. Since the outer ring cover 4 is mostly covered by the direct cover to cover the gas stove seat 1, there is no mutual locking function, so that the internal gas can easily escape from the gap. The phenomenon of uneven gas supply, endocytosis or gas explosion occurs, and the gas is leaked out from the gap, so that the interior thereof naturally forms a disturbing flow of mutual impact, thereby forming a situation in which the combustion of the gas is uneven. In addition, since the above-mentioned deficiency is used, the flame easily escapes outward, resulting in inhomogeneous heat conduction, and the combustion efficiency is poor, so that there is a waste of gas, a long cooking time, and the like.

Therefore, how to develop a gas stove joint structure, which can solve the above defects is the motive for the research and development of the invention.

The second intake end 141 is delivered to the outer ring cover body 30 such that the gas is ejected from the flame by an outer ring cover hole 33.

It can be seen from the above components and implementation description that the present invention has the following advantages as compared with the prior art:

First, the structure is simple and integrated and easy to install. The furnace seat body 20 and the outer ring furnace cover body 30 of the invention are integrally formed, and the two components are combined into a single component, and the three components are required to be divided into a top plate and a chassis and an outer ring cover according to the prior art. The invention has the advantages of relatively economical mold and production cost, and the quality control process is also less time-saving, the structure is simple and easy to install, and the single fixing step can be installed on the mixing tube 10 to achieve extremely simplified and simplified back-end processing, and the manufacturing is fast and easy. efficacy. In addition, since the furnace seat body 20 is integrally formed, it is possible to prevent the soup from dripping to the furnace seat body 20, which is difficult to clean, and the convenience in use is further increased.

Second, the adhesion is increased to prevent the turbulence caused by the collision of each other when supplying air. When the gas stove is used for a long period of time, the wear of the gas stove seat 1 and the outer ring cover 4 is often formed by the use of the disassembled and disassembled after the assembly, and the gas stove is formed. When the seat 1 and the outer ring cover 4 are closed, there is no direct locking and strengthening, so that the gas in the gas chamber can be easily leaked out from the gap, so that uneven gas supply, endocytosis or Gas explosion and other phenomena occur. Therefore, the present invention improves the above-mentioned defect by the first sealing surface 241 of the furnace seat body 20 and the second sealing surface 321 of the outer ring furnace cover body 30 abutting each other, and the plurality of screws 40 are locked by the plurality of screws 40. The furnace body 20 and the outer ring cover body 30 make the first sealing surface 241 and the second sealing surface 321 more compact and compact, so that when the burner body 10 is supplied with air, it does not interfere with each other. Flow and uniform supply of gas for combustion purposes.

Third, strengthen the combined structure. The outer ring cover 4 is directly attached to the gas stove seat 1 and does not have any reinforcing structure, so there is a disadvantage that the strength of the outer ring cover 4 is slightly damaged, and the outer ring cover 4 is slightly damaged. The gas furnace seat 1 is separated. Therefore, the present invention is locked to the screw hole 243 and the screw hole groove 323 by the plurality of screws 40, so that the outer ring furnace cover 30 and the furnace seat body 20 are completely in close contact with each other. The ring cover 30 is not separated from the hob body 20 by a slight impact. In addition, the plurality of screws 40 lock the furnace seat body 20 and the outer ring furnace cover body 30, which is convenient for simple wiping and finishing in a plane manner after the cooking is completed, so as to completely solve the conventional need to be cooked. Afterwards, pay special attention to finishing the leftover ingredients in the recessed space to achieve a more simple cleaning effect.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the equivalent equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still The scope of the invention is covered.
