Abstract

PURPOSE:To safely and reliably produce calorific value, optimum to cooking over a slow fire, without dying of flame, by a method wherein a guide plate is constituted such that it has a gap, being sized to be slightly wider than the width of a control lever, and a crank-shaped guide groove is provided in a direction in which the control lever is slid. CONSTITUTION:Since a guide groove 8 is formed in the shape of a crank, even if a control level is rapidly lowered downward, it stops to a point Y. The point Y is set to about 850kcal/h which is not included in a back area. Since the control lever is moved to a next guide groove after it stops to the point Y, the next groove is displaced slightly sideways. Thereafter, the control lever is further pressed downward to produce a given slow fire, i.e., 300kcal/h. A change in a primary air is such that the air amount is changed into an ordinary value balanced with a gas amount during sideways displacement of a control lever 1. Further, even if the control lever is rapidly moved to slow fire calorific, value, since a change amount is low, an amount of the air is not increased to an excess air, but is brought to a point C, and this causes continuance of combustion without dying flame.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a lever device for a fire power adjustment device for a gas appliance tap.

Structure of conventional example and its problems For example, in the past, for example, the lever sliding device of the fire power adjustment mechanism installed on a gas staple stove is either on one side of the stove as shown in Figure 1, or on the left or right side as shown in Figure 2. As shown in FIGS. 5 and 6, the guide groove 8 of the guide plate 7 on which the operating lever 1 slides is attached to both sides of the stove. The width was slightly wider than the operating lever 1], and it had a simple longitudinal groove.

Many gas staple stoves with a fire power adjustment structure have been released in recent years, mainly for 13A and LPG gas stoves, which are difficult to adjust fire power. It has been well received because of its ability to

However, most gas staple stoves currently on the market with sliding firepower adjustment mechanisms have the following drawbacks. ■ When switching from high heat to low heat, if you operate the control lever quickly (0.1 to 0.3 seconds), the fire will go out and raw gas will continue to come out.

Or, in order to eliminate the above phenomenon, the calories necessary for the fire to go out cannot be obtained. There are drawbacks such as.

The reason why the fire goes out when operating lever 1 is operated quickly is as follows.
This will be explained using FIG. 11 and FIG. 12.

FIG. 11 is widely known as a combustion characteristic diagram of a combustion flame. FIG. 12 is a characteristic diagram regarding the fire extinguishing process. A Bunsen burner shown in FIGS. 7 and 8 is usually used as a burner for a gas staple stove. In FIG. 12, the primary air suction capacity of the gas burner, which has a combustion capacity of gas consumption of 2,200 Kcal/h during high flame combustion, is about 50% of LPG, and this is shown at point A. −The next air is
In the case of a Bunsen burner, the higher the gas ejection pressure, that is, the higher the gas consumption, the more the primary air intake port 1 of the Bunsen burner.
More than 1 inflow. Now, if you suddenly switch the operating lever 1 from high heat to low heat, the gas consumption will decrease according to the operating lever, but the negative air volume cannot change rapidly due to the residual momentum during high heat, and the gas consumption will decrease. On the other hand, there is an excess of air, which reaches point B, enters the puncture area, backs up, and extinguishes the flame.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and aims to safely and reliably obtain the optimal calories for slow-cooked dishes without extinguishing the flame.

Structure of the Invention In order to achieve the above object, the lever device of the fire power adjustment mechanism of the present invention comprises a gas appliance tap body, an operating lever for adjusting the fire power that is linked to the appliance body, and a part of the appliance body that guides the operating lever. The guide plate has a gap slightly wider than the width of the operating lever, and has a crank-shaped guide groove in the direction in which the operating lever is slid. .

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

Figures 1 and 2 are external views of a gas staple stove.
The appliance tap with fire power adjustment shown in Figs. 3 and 4 is incorporated. After opening the appliance plug knob 3 to ignite and burn the burner, the guide groove 12 of the guide plate 7 built into the appliance body
Move the operating lever 1 that slides to switch from high heat to simmering heat.

5'・-) The guide groove 12 has a crank shape, and even if the operating lever is suddenly lowered, the Y shown in FIGS.
Stop at a point. A diagram of changes in gas consumption and changes in air amount at this time is shown in FIG.

The Y point is set at about 850 Kcal/h, which does not fall into the back range. After the operating lever stops at point Y,
As shown in the figure, shift it slightly laterally to move to the next guide groove. Thereafter, it is further pushed down to obtain a predetermined simmering calorie (300 Kcat/h). 1st
As shown in Figure 2, the change in the -order air amount is controlled by operating lever 1.
While moving the air to the side, the amount of air changes to the normal amount that matches the amount of gas. Furthermore, even if the operating lever is rapidly moved to reach a simmering calorie, the amount of air does not become excessive because the amount of gas change is small, and reaches the 0 point and continues combustion without extinguishing the flame.

Effects of the Invention As described above, according to the present invention, the following effects can be obtained.

(1) Even if the operating lever is operated suddenly, the flame will not go out.

6 ゝ- (2) The optimum calorie for simmering (approx. 300-400K)
cal/h) can be obtained.
