Description

Easy remove of scale in gasrange overheat check system

The present invention relates to a gas range overheating device that can be easily descaled. In the use of the gas range, cooking vessels were placed on the table, and people went home forgotten or even went out, leading to fire due to overheating.

To this end, in the prior art, the cooking time is counted after the burner is ignited to generate an alarm sound when the counted cooking time elapses, and the user is required to take necessary actions and the switch is turned on even after a predetermined time. If it is maintained, the domestic pre-registered patent No. 0783343 of the method of stopping the gas supply by turning off the solo valve by the user judged as absent, and the temperature sensor measures the temperature of the grill part and the temperature of the grill part is In the case of the rise, there is also the Korean Patent No. 187056, which switches the combustion mode of the grill burner from the mode selected by the user to prevent the sudden rise of the grill part to prevent damage to the peripheral parts of the grill part. The problem is that the average cooking time is different for each food, so the user has to set the proper cooking time. In this case, the control of the average cooking time for each food is inaccurate and the temperature sensor unit for detecting temperature overheating is fixed in a state close to the flame, so that the overheat state of the food accumulated in the cooking container can be efficiently measured. In the first application, the expansion chamber is swollen by heating the flame as a means of detecting and measuring the direct overheating of the cooking vessel. After the device checks the temperature in a state close to the bottom of the container and safely shuts off the gas supplied to the gas range, the temperature detecting element cap portion is in contact with the burner nozzle position and the bottom of the cooking vessel. If a scale is formed at the end of the temperature detecting element cap, an error occurs in the temperature detection. In order to prevent this, there was a inconvenience to keep it clean after cooking the gas range.

The present invention has been devised in view of the above, and the temperature detecting element cap portion rises from the burner nozzle position to be in contact with the bottom of the cooking vessel, not driven by an electric method, but by heating of the gas range. Following the up-and-down expansion movement of the installed expansion chamber, it provides a system that leads to the rotational movement force so that the superheat of the gas range is directly in contact with the bottom of the cooking vessel and then rotated again so that the scale formed on the temperature detecting element cap is removed at the same time. It relates to a range overheat protection device.

Looking at one embodiment configuration and operation of the present invention configured for the above purpose by the accompanying drawings, the gas supply nozzle bundle 27 installed below each burner nozzle (3) of the conventional gas range body (1) The upper and lower ends of the frame 15 installed at a predetermined distance are embedded in the periphery 25 of the lower end of the frame 15 with three tension adjustment screws 14 embedded in the outer periphery of the lower contact spring plate 13. Three bottom ball bearings 11 'are formed in the flange, and the bottom outer periphery of the heating plug installation cylinder 11 having the spiral groove 12' is formed on the side, and the heating plug installation cylinder 11 is welded to the upper outer periphery. A small hole is formed, and a heating plug 9 having a heating plug spiral groove 9 'formed therein is installed at a lower end thereof, and a scale removing groove 5' is formed at an upper side of the upper inner side of the inner cavity of the heating plug 9 formed therein. Of the temperature sensing element cap 5 on which the legs are formed and the legs 5 'are formed on the bottom surface thereof. The seal cap 21 is fixed by welding, and a temperature detecting element 6 is inserted below the temperature detecting element cap 5, and the temperature detecting output terminal 7 is drawn out of the upper dome of the expansion chamber cap 21. By passing through the terminal fixing element 8 fixed to both upper ends of the pollution prevention plate 10 welded to the intermediate end of the heating plug (9) to the outside, and the inner tube of the heating plug (9) In the expansion chamber cap 21 fixed at the upper end, a dome-shaped hollow portion is formed at the upper end, a bellows-type expansion chamber 20 is formed at the lower end, and a safety valve at the outer circumference at which the safety valve installation recess 24 'is formed at the upper end. The rotating shaft 18 having the 24 formed therein is inserted into the lower shaft by the rotation shaft fixing plate 19 and assembled with a fixing nut 23 at the bottom thereof to form a '[' type leaf spring holder 17 on the rear surface of the frame 15. Fixed one end of the leaf spring (16) formed in the middle to the lower portion fixed to the formed on the upper side fragment Mounted on the groove (16 '), the one end of the rotating shaft fixing plate 19 is bolted to the terminal fixing lower element (7') of the lead wire of the temperature detection output terminal (7), but the safety valve of the rotating shaft (18) (24) The slider pin 12 is fixed through the lower shaft portion and flows out into the spiral groove 12 'portion.

Looking at one embodiment of the present invention configured as described above, first, the assembly installation of the present invention, as shown, the frame spaced apart installed in the inner space of the lower base 4 of the conventional gas range body (1) ( The heating plug (9) and the temperature detecting element cap (5) installed in (15) are positioned so as to be located at the center of the gas supply nozzle bundle (27).

The distance between the temperature detecting element cap 5 and the cooking vessel 26 installed above is in the thermal expansion of the expansion chamber 20 formed on the upper shaft of the rotating shaft 18 mounted on the groove 16 'of the leaf spring 16. By the assumption that the edge of the heating plug base (9 ') should be installed equal to the expansion distance to reach the lower end of the heating plug installation cylinder (11).

In addition, the reaction force raised by the heating plug 9 by the force due to the thermal expansion force of the expansion chamber 20 should be less than the buffering force of the leaf spring (16).

Therefore, while the user opens the gas valve adjusting cock 28 to ignite the flame in the cooking vessel 26 to cook, the heating plug 9 having a small hole in the outer wall is heated to heat the upper dome and the expansion chamber formed therein. When the thermal expansion 20 is, the heating plug 9 is primarily heated to heat the upper dome and the expansion chamber 20 inside the heating plug 9 mounted on the upper axis of the rotary shaft 18 mounted on the leaf spring 16 The temperature detecting element cap (5) inserted in the) is raised to come in contact with the bottom of the cooking vessel (26).

While being cooked in contact with the bottom, the user inadvertently goes out, and the temperature detecting element cap that touches the bottom of the cooking vessel 26 before the overheated temperature detection value reaches the preset overheat cutoff temperature value ( 5) The scale removing groove 5 'formed at the upper side of the cooking chamber has a reaction force that the expansion chamber 20 continuously expands vertically due to overheating. From the point where it is obstructed by the bottom of the container 26 and cannot progress upward, the rotating shaft 18 placed on the groove 16 'of the leaf spring 16 overcomes the buffering force of the leaf spring 16 and vertically expands downward. At this time, the heating plug spiral groove (9 ') formed in the lower portion of the body heating plug (9) penetrated to the upper shaft end of the rotating shaft 18 and the spiral groove 12' formed in the heating plug installation cylinder (11) The slider pin 12 is installed in the flow to the spiral groove 12 ' La is moved.

The slider pin 12 rotates the heating plug 9 in a clockwise direction while moving along the spiral groove 12 'which is a spiral closing section, so that the scale removing groove 5' is formed at the upper end of the temperature detecting element cap 5. The scale of the bottom of the cooking vessel 26 in contact with the portion is removed by rotational friction and at the same time detects the overheat cut-off temperature value of the cooking vessel 26, thereby detecting more accurate temperature and measuring it on the processor of the display unit 29. The gas supplied to the gas supply nozzle bundle 27 by providing the temperature value is safely turned off by the solenoid valve (not shown).

When the flame is turned off and the heating plug 9 is cooled, the expansion chamber 20 contracts again, and the heating plug 9 contracts downward in a state as shown in FIG. 3 to be spaced apart from the bottom of the cooking vessel 26. It will be recovered.

One embodiment effect of the present invention is configured as a temperature measuring means of the overheat prevention device adopted in the conventional gas range, out of the gas valve control method by the proximity measurement method, the first vertical rise and 2 depending on the degree of heating The present invention provides a means for accurately detecting the overheating of the cooking vessel 26 by the lowering of the rotation and accurately measuring the presence of overheating, and also the bottom of the cooking vessel 26 and the temperature element cap 5. Scales such as soot formed on the upper end is a useful device that is removed at the same time.
