Description

GRADUAL FURNACE TAP WITHOUT THERMOSTAT FOR GAS-FIRED FURNACES

TECHNICAL AREA

This invention relates to a safe gas valve that allows flow that can keep the temperature inside the furnace constant in a certain period without the need for a thermostat system for operating furnaces, that can be cooked by obtaining different levels of power with multiple flame lengths that can be obtained during combustion thanks to the level system it has, and thus allows operation without having a thermostat system instead of thermostat gas taps in the furnaces.

BACKGROUND OF THE INVENTION

The appliances that direct the gas in the domestic cooker and ovens are called gas valves. Although an electric system is used in our country, especially in ovens, gas- powered ovens are used in many parts of the world. Since cooking takes place in a closed environment in ranges, keeping the temperature inside the oven under control is necessary. Gas taps carry out this control with a thermostat system in the current system. Depending on the temperature inside the range, gas taps with thermostats increase and decrease the flow rate volume that passes to the combustion burners.

In domestic gas-fired ovens, the thermal power control required during cooking is provided by gas taps with a thermostat system. A particular bulb placed in the range is integrated into the faucet system so that the required gas flow rate can be adjusted and controlled for the thermal power that will ensure the temperature inside the oven. Thanks to the bulb passing through the tap according to the temperature inside the range, the flow rate can increase and decrease, and thus, the temperature inside the oven can be kept between certain levels. In this existing thermostat system, problems such as the difficulty of temperature adjustment, the supply of the bulb, and the high manufacturing costs are encountered.

In classic combustion faucets, the flame lengths are maximum and minimum. The flame lengths between maximum and minimum in the taps peak at the flow rate drop at the stage transitions, preventing controlled temperature drop in temperature deceleration. This situation leads to an unstable system for adjusting the temperature inside the oven.

The thermostat oven valve is a valve that you manually adjust to control the oven temperature (oven heat knob). The temperature-sensitive bulb used to manage the oven’s temperature causes technical problems such as loosening or inability to function with combustion.

Although there are many gas tap alternatives in different structures, features, and designs in gas-powered furnaces, the only system used for current temperature control in gas ovens is the bulb-controlled system, and there is no alternative.

The application CN103574087B mentions a temperature control valve for gas furnaces. The system mentioned in this application comprises a valve body, valve cap, stem, thrust spring and a valve element. The valve body is supported by a gas inlet channel and a gas outlet channel. The said valve element is connected with the gas inlet duct and the gas outlet duct. There are guide holes on the valve element, divided into two parts: the guide holes and the guide holes. The up guide holes and down guide holes match the pleasure supply passage. The up-guide hole is connected to the gas outlet section, and the down guide hole is connected to the lower cavity. A sealing element is provided on the connection between the disc base of an adjusting rod and a thread portion and is mated with a screw hole. The lower end of the shaft enters the gas outlet space to be matched with a gas outlet hole; the lower end of the print spring is compatible with the disc base. In this way, the gas temperature control valve regulates the adjustment shaft of the gas entering. The gas flow can be handled by the rotation of the valve element so that the different gas output quantities are precisely controlled to reach a required temperature. The lower end of the print spring is compatible with the disc base. The gas temperature control valve is regulated by the adjusting shaft of the gas inlet quantity. The amount of gas loading can be handled by rotating the valve element. Therefore, it is possible to precisely control different gas output quantities to reach a required temperature. In this system mentioned in this application, a conical male is mentioned with a valve element. We see that the holes on the taper are lined up parallel to each other at the bottom and top to adjust the gas output flow rate so that their diameter decreases. With the rotation of the shaft, the desired output flow rate is achieved using the hole diameters. However, in this system, when it is expected to increase and decrease the temperature inside the furnace, the gas supply channel corresponds to a single hole by turning the shaft. When the temperature is desired to reduce, it provides a sequential decrease in the case of turning the post. In contrast, it cannot give a temperature distribution in an equal angle division and does not solve the "peaking" problem. However, the invention relates only to the gas flow from the outlet duct to the combustor and does not offer a solution to keep the in-furnace temperature within a specific temperature range and again reveals a gas valve that requires a thermostat system.

DESCRIPTION OF THE INVENTION

The present invention relates to a gas tap that allows multiple flame stages to provide the temperature in the furnace by obtaining the necessary thermal power without the need for thermostat adjustment, and that maintains the temperature value in the furnace at the desired level by precisely flowing at different flow volumes depending on the rotation angle of the tapped shaft through the furnace tap.

The gas tap subject to the invention is a gas tap that allows adjusting the degree of rotation of the tapped shaft for the appropriate thermal power by calculating and determining the flow amount that must pass through the tap at the unit time to obtain the necessary in-furnace temperature for different foods with the studies.

The present invention also relates to a tapered part having specially designed holes that provide the flow obtained according to the angle of rotation of the tapped shaft. This invention is related to a safe gas tap that allows flow passage that can keep the heat inside the oven at the desired temperature without the need for a thermostat and the bulb.

The invention is a gas tap that allows the temperature in the oven to be achieved by obtaining the necessary thermal power without the need for thermostat adjustment by obtaining multiple flame levels.

Another feature of the invention is that it is a furnace gas tap through which the temperature inside the furnace can be kept at the desired level by precisely flowing at different flow volumes depending on the rotation angle of the tapped shaft. Another feature of the invention is that it is a furnace gas tap that determines how many degrees of rotation of the tapped shaft for appropriate thermal power by calculating the amount of flow that must pass through the tap in unit time to obtain the necessary in-furnace temperature for different foods.

The present invention also relates to a specially designed tapered part that provides a safe gas tap design that allows the flow passage that can keep the heat inside the oven at the desired temperature without the need for a thermostat and the bulb by providing the flow obtained according to the rotation angle of the tapped shaft through the tap.

Decoupage in gas ovens ranges from 280° to 120°. There are seven different cooking temperature levels in the intermediate values in 5 total. This invention relates to an oven gas tap that provides more precise and effective cooking by increasing seven different cooking temperatures to 9 levels. In this way, additional thermal power is obtained at each different flow rate, and a stable temperature in the furnace is provided.

This invention is related to a gas tap that provides temperature control in the oven by preventing an excessive oven temperature during long cooking times.

The invention of the gas tap is related to a gas tap made of brass or aluminium material that can obtain nine different thermal power with nine different combustion stages. It prevents the problem of the flame peaking while the stage is changing, that is, during the transition between the sets. Thanks to the placement of the steps on the male conical, temperature distribution can be made in equal angled divisions. Thanks to the order of the stages on the conical male, the temperature sensitivity in state of the art are ±15 degrees, while in this invention, the sensitivity is ±5 degrees. Thus, with the temperature change sensitivity it provides, it can be ensured that the temperature for the furnace is more stable.

The gas tap, the subject of the invention, can achieve the problem mentioned above solutions thanks to the sensitivity of the hole in the conical.

Another feature of the invention is that it can be divided into equal intervals and provide temperature change distribution in equal parts in all different studies.

This invention solves the problem of peaking, as the holes see different outlet holes simultaneously in the gas outlet hole of the body during the flow rate decrease. DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

The gas tap (1 ), designed for use in domestic and industrial gas ovens, generally consists of a gas inlet (2.1 ) and one or two gas outlets (2.2) of the tap body (2), shaft (7), multistep cover (8), pin (6) consists of assembling the safety valve (13), the tapered element (3), the union (14) and the intermediate sealing elements.

In Figure 1 , there is the gas tap (1 ) structure, which includes all the system elements. The tapered element (3), seen in perspective view in figure 3, together with the system elements in the exploded picture in Figure 2, is an aspect that provides gas regulation to allow temperature changes in the furnace. The inlet (2.1 ) is in the form of an opening that supplies the gas inlet and provides gas passage to the tapered element (3) in the gas tap (1 ). The outlet (2.2) is an opening that provides the transmission of the gas coming with the gas inlet to the combustion section, and this opening matches the holes (3.1 ) of the tapered element (3) that will adjust the temperature according to the desired level. The multistep cover (8) provides sealing by closing the tap body (2), and with its gradual structure enables the temperature level to be noticed at the temperature transitions. The shaft (7) connected with the cooker knob allows the user to rotate the gas tap (1 ) in the tapered element (3) connected to them when they turn the knob clockwise or counterclockwise, allowing the transition to the flame levels between the maximum and minimum caused by the gas passage. The stages on the multistep cover (8) provide a sense of sound and sensory vibration.

Elements such as segment (12), switch washer (11 ), spring (10) meet the pressure exerted by the user by turning the cooking knob. With this pressure, the pin (6) is pushed, allowing the tapered element (3) to rotate in a guided manner, thanks to the slot-shaped channel on it when the user turns it over. The conical pressure spring (5) enables the pin (6) to return to its initial level when the user pulls the pressure, and the washer (4) is an intermediate element that also meets the pressure.

The present invention relates to a gas tap (1 ) and the working principle of the gas tap (1 ), which includes a tapered element (3), which allows the temperature in the furnace to vary in the range of only ±5 °C in connection with the diameter sensitivity of the holes in the furnace to be at any desired temperature option; while rotating to provide flow adjustment for the temperature change of the tapered element (3) with the transition between the steps, always two holes (3.1 ) appear in the opening of the outlet (2.2) and thus the gas passage through the opening with two holes (3.1 ).

When the user presses the temperature adjustment button, the projection on the shaft (7) moves to the corresponding slot on the tapered element (3). As the user starts to turn the pressed button, the tab on the cap washer (9) starts to move between the steps, while the tapered element (3) starts to rotate in the tap body (2) together with the shaft (7). With this rotation, the gas coming from the opening at the inlet (2.1 ) exits from the gas opening at the outlet (2.2) through the holes (3.1 ) on the tapered element (3).

The holes (3.1 ) on the tapered element (3) give the location of one of the two holes visible from the rotation and outlet (2.2) opening to the hole behind or in front of one another to reach the target temperature with equal angled divisions concerning the temperature changes required for the furnace to be used, while at the same time starting to be visible from the opening in a third hole (3.1 ) and finally being located in the outlet (2.2) of two different holes that will provide the desired target temperature output. The peaking problem is solved by the simultaneous appearance of different outlet holes (3.1 ) in the body gas outlet (2.2) opening at the flow rate drop of the holes (3.1 ). In this system, equal distribution can be achieved in all different studies. In this way, the working angle of the valve is equal in serigraphy; it is in the range of 0°-210°, 0°-231 °, 0°-270°.

The sequential holes (3.1 ) on the tapered element (3) are placed in pairs to the opening at the outlet (2.2) with the rotation of the user, and this prevents the occurrence of the peak problem in the flow rate decrease. The flow rate drop graph seen in Figure 5 shows that the outlet (2.2) opening makes a stable decrease without peaking. In contrast, the outlet (2.2) opening allows the holes (3.1 ) to pass bilaterally without closing, even momentarily, with the rotation of the tapered element (3).

In the graph shown in Figure 6, it can be seen that the target temperature is reached within a range not exceeding ±5°C with only minimal deviations thanks to the hole (3.1 ) diameter precision.
