Abstract

PURPOSE:To enable either a right or a left burner by preference of a user to work as a high calorie burner, by a method wherein an on-off valve, mounted within a gas nozzle support, is designed to have a size relation, between a nozzle support seal part and a gas nozzle, in that the on-off valve is not opened until the gas nozzle is sealed. CONSTITUTION:When a burner 16 is disconnected from a gas cock 6 side, since a gas nozzle 14 is secured to a damper 15, the nozzle is disconnected simultaneously, an on-off valve 8, sized to be the width of a nozzle support 7, is brought to a closing state to prevent leakage of gas. Since the size of a part B of the gas nozzle 14 is shorter than that of a part A of the nozzle support 7, the on- off valve 8 is brought to an opening state only while there is a size in that the gas nozzle 14 can be sealed by a seal rubber 13, and the on-off valve 8 is closed when the gas nozzle is brought to a condition in that it parts from the seal rubber 13. The amount of gas consumed is determined by the gas nozzle 14, it is necessary that the burner 16 and the damper 15 match the amount of gas consumed, and they are integrally mounted and demounted, whereby mutual discordance is prevented from occurring.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a gas burner in which the gas consumption of left and right gas stoves in a gas stove and the burners can be easily interchanged.

Conventional configurations and their problems In what is generally referred to as a gas staple, which consists of two or more gas stoves, the gas consumption amounts of the left and right gas stoves are often different. Therefore, during manufacturing, the gas consumption amount of the right or left gas stove section is determined in advance. For example, the gas stove on the right side is 2800 KO depending on the manufacturer.
2 Ll/h and left side gas stove 2000 Kcal/h
It is customarily determined that. However, in a typical home, there is a wall on the left side or a wall on the right side where the gas stove is placed, and if the high-calorie gas stove is on the wall, when using a large pot, the pot If it hits the wall, it may interfere with cooking, the wall may become hot, and there is a risk of fire. Also, depending on the user's preference, it is possible to decide which side of the high-calorie gas stove is better, the left or the right. Therefore, when purchasing gas stoves, consumers often find that their preferred manufacturer's product has a gas stove with a large calorie content, which they do not like.

Therefore, in order for manufacturers to meet consumer demands, they must offer two types of gas staples, one on the left or one on the right, with a high calorie content. There are many models that are compatible with various types of city gas including LPG, and making two types of high-calorie gas staples on the left and right would double the number of models and be an economic waste, so in reality, the side with the high-calorie stove is I decided on one type. Therefore, modifications and changes may be required to meet consumer demands, which is time-consuming. In other words, in order to modify a conventional product, as shown in Fig. 1, a gas nozzle 2 is screwed onto a gas cock 1 using a threaded part 3, and a damper 4 and a burner 6 (only a portion is shown) are inserted into the gas nozzle 2. First, remove the burner 6 and damper 4 from the nozzle 2 screwed on the gas cock 1, then remove the gas nozzle 2 screwed on the threaded part 3 of the gas cock 1, and then replace the same type on the opposite side. The gas nozzle, burner, and damper parts need to be replaced.

A gas leak prevention sealant (not shown) is used on the threaded part 3 to prevent gas leakage when the gas cock 1 and gas nozzle 2 are screwed together. Needs to be inspected.

OBJECTS OF THE INVENTION An object of the present invention is to enable, for example, in a three-day gas staple, when the left and right burners have different calories, either the left or right burner can be easily changed to a high-calorie burner according to the user's preference.

Structure of the Invention The structure of the present invention is such that a damper and a gas nozzle are fixed or integrated with a burner, and the gas nozzle is fitted into a nozzle receiver provided on the downstream side of a gas cock, and the gas nozzle receiver is provided with an opening/closing mechanism provided inside the gas nozzle receiver. The valve is a gas combustor such that the opening/closing valve does not open until the nozzle receiver is sealed between the seal portion and the gas nozzle.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below. FIG. 2 shows the configuration of the present invention, in which a nozzle receiver 7 is screwed onto a gas cylinder, an on-off valve 8 is located inside the nozzle receiver 7, and a valve rubber 9. There is a valve rubber receiver io, a valve spring 11, and a valve seat 12, and a seal rubber 13 near the nozzle receiver 70 inlet also seals the dovetail gas nozzle 14.

The gas nozzle 14 is caulked to a damper 16, and the damper 16 is fixed to the burner 16 (only a portion is shown) with screws 17. FIG. 3 shows a state in which the damper 15 is fixed to the burner 16 and the gas nozzle 14, which is fixed to the damper 16, is separated from the nozzle receiver 7, and the on-off valve 8 is in the closed state.

Further, the dimensions of the A section of the nozzle receiver 7 and the dimensions of the B section of the gas nozzle 14 have a dimensional relationship of A)B (B==C-1-D, therefore A>C). Since the present invention has the above-described configuration, the burner 16 of the present invention can be installed from the gas stapler side in the same way that a consumer of a general gas staple sometimes removes the burner 6 from the gas nozzle 2, cleans it, and reinserts it into the gas nozzle 2. When removed, since the gas nozzle 14 is fixed to the damper 16, it will come off at the same time, resulting in the state shown in FIG. By chance, Figure 3 shows the gas valve in the open state, but the nozzle receiver 7-width on-off valve 8 is closed to prevent gas from leaking. Since the B part and 0 part of the gas nozzle 14 are smaller than the dimension of the A part of the nozzle receiver 7, the on-off valve 8''f: is opened only when the gas nozzle 14 can be sealed with the seal rubber 13 of the nozzle receiver 3, and the gas nozzle 14 is closed. When the receiver 7 is separated from the seal rubber 13, the on-off valve 8 closes as shown in Fig. 3. Also, the seal rubber 13 is made of a heat-resistant and slippery rubber such as fluoro rubber, which improves sealing performance and durability. Since the gas nozzle 14, damper 15, and burner 16 are integrated, the part that has a factor that determines the gas consumption, that is, the gas consumption, is determined by the gas nozzle 14, and the burner 16 and damper 15 determine the gas consumption. Since they are removed and installed as one unit, there will be no mismatch between the burner 16, gas nozzle 14, and damper 16. Therefore, if you accidentally remove the burner 16 and mistake it for the left or right front shoulder. Even if the gas nozzle 14, damper 16, and burner 16 are installed together, unsafe combustion of gas will not occur and the combination of parts can always be maintained for safe combustion. Replacement can be done easily and safely by consumers in the same way as attaching and detaching common commercially available safety gas sockets.

Effects of the Invention As described above, the present invention provides a gas staple with a large calorie burner and a standard burner, for example, 2B 00 KOal/h and 2000 KOal/h burners, and a nozzle fixed to the burner with a damper and a nozzle connected to a gas cock. When inserted into the receiver, the nozzle receiver and nozzle are sealed, and the on-off valve is then opened.Since the nozzle, damper, and burner are integrated, the burner, nozzle, and damper can be attached to either the left or right. There is no accumulation and normal combustion is guaranteed. Rather than using separate parts, the on-off valve is opened and closed by the nozzle necessary for combustion, and by utilizing some of the dimensions of the nozzle, the on-off valve can be opened after completing the seal between the nozzle receiver and the nozzle. I have to. Therefore, the on-off valve is constructed so that the on-off valve does not open when the nozzle is not fully inserted into the nozzle receiver, and this is done in consideration of safety.

Therefore, consumers can freely exchange the left and right burners and clean them, and manufacturers can obtain a very economical gas combustor without having to make appliances with two types of large-power IJ-burners, left and right.
