Description

Gas kitchen ranges

Technical Field

The embodiment of the application relates to the field of household appliances, in particular to a gas stove.

Background

With the increasing living standard of people, gas stoves have already entered thousands of households. The safety of the household gas cooker is also increasingly emphasized.

Current gas cookers include a flame sensor that detects a flame value and determines whether there is a flame by comparing with a set flame threshold. If the flame value is larger than the flame threshold value, the flame is judged to be existed, otherwise, the flame is judged to be absent.

Different gears are usually provided in gas cookers, for example a low gear for low fire and a high gear for high fire. These gears correspond to the same flame threshold, for example set at the factory. However, different gears have different effects on the detection value of the flame sensor. In the ignition stage, if the set flame threshold value is high, even if a flame is actually generated, it is erroneously judged as no flame because the flame detection value of the flame sensor is lower than the flame threshold value, which causes a longer ignition time and thus a longer duration of (ignition) noise. In the low gear, the actual flame detection value is lower than the set flame threshold value, which may cause the flame to be erroneously determined as flameout.

On the other hand, if the set flame threshold is low, the actual flame detection value exceeds the set flame threshold too much in the high gear, thus causing too long a valve closing time in the event of accidental flameout, which results in more gas leakage and thus a safety hazard.

Therefore, there is still a need for continued improvement in respect of at least some of the above problems, and in particular there is still a need for a gas burner which is easy to operate and safe and reliable.

Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and exemplary embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and do not limit the scope of the present application.

For a better understanding of the gas cooktop described above, exemplary embodiments of the present application will be described below with reference to the accompanying drawings. It should be noted that the directional terms used in the description refer to the conventional use of the gas range for the convenience of description and are not to be understood as an absolute definition of the corresponding features.

Fig. 1 shows a perspective view of a gas range according to an embodiment of the present application. An X-Y-Z coordinate system is shown in the drawing, wherein the X direction represents a direction toward a user, the Y direction represents a width direction of the gas range, and the Z direction represents a height direction of the gas range. As shown in the drawings, the gas range 1 includes a range body 10, a combustion device 20, a gas delivery assembly (not shown), and a plug valve 40 integrated with a solenoid valve function.

The stove body 10 illustratively includes a panel 100, e.g., a glass panel, and a housing 101. A housing 101 is attached to the underside of the panel 100 and serves to house gas delivery components, control devices, alarm devices, etc., which are not shown. The combustion device 20 is disposed on the panel 100 of the range body 10 and serves to receive gas from the gas delivery assembly and to perform combustion. The stop cock 40 is arranged on the front portion of the panel 100 in the X direction and has different gears for adjusting the amount of gas delivered to the combustion device 20. According to this exemplary embodiment, the gas cooktop 1 is designed as a built-in gas cooktop 1 and has, for example, two combustion devices 20 and, correspondingly, two stop cocks 40, with the two combustion devices 20 and the two stop cocks 40 each being arranged mirror-symmetrically with respect to a center plane (plane parallel to the XZ) perpendicular to the cooktop body 10 or the face plate 100.

Fig. 2 shows an interior perspective view of the gas burner 1 from fig. 1. As shown, the gas range 1 further includes a position sensor 50, a control device 60, an ignition device 70, a flame sensor 80, and a not-shown alarm device.

The position sensor 50 is configured as an angle sensor 50, for example, and detects the rotation angle of the plug valve 40. Since different rotation angles of the plug valve 40 correspond to different shift positions, the position sensor 50 can detect and generate a shift signal of the plug valve 40. In this embodiment, the position sensor 50 is arranged coaxially with the valve shaft of the stop cock valve 40 on the lower side of the stop cock valve 40. Alternatively, the position sensor 50 can also be integrated into the stopcock valve 40.

The ignition device 70 is designed, for example, as an ignition needle 70 and is arranged in the combustion device 20 for igniting the gas supplied to the combustion device 20. The flame sensor 80 is designed as a thermocouple 80 and is arranged in the combustion device 20 adjacent to the ignition device 70 for detecting the detection of the combustion device 20 and generating a flame signal in the form of a temperature or a voltage. In this exemplary embodiment, a respective ignition device 70 and flame sensor 80 are arranged in the two combustion devices 20, and the two stop cocks 40 are assigned a respective position sensor 50.

The alarm device (not shown) is used to output an alarm signal, such as a light signal, a sound signal, or a combination thereof, for example, in the event of an accidental extinction of a flame or a prolonged fire.

As can also be seen, a control device 60 is accommodated in the housing 101, the control device 60 being arranged centrally with respect to the two combustion devices 20 and being electrically connected to the position sensor 50, the ignition device 70, the flame sensor 80, the alarm device and the stop cock 40. In this embodiment, the control device 60 is used to acquire a gear signal from the position sensor 50 and to set a flame threshold accordingly and to output a corresponding control signal in the operating state of the gas burner.

The plug valve 40 includes a solenoid 400. Upon depression of the valve stem of the stop cock valve 40, the solenoid 400 is energized to cause the stop cock valve 40 to open and deliver gas from the gas delivery assembly 30 to the combustion device 20. In the event of an accidental flame-out of the combustion device 20, the control device 60 outputs a valve control signal to the plug valve 40 and the solenoid 400 is de-energized, thereby closing the plug valve 40.

Fig. 3 shows a schematic connection diagram of a control device 60 of the gas range 1 according to an embodiment of the present application. As shown in FIG. 3, the control apparatus 60 includes a threshold setting module 601, an ignition control module 602, an alarm module 603, and a valve control module 604.

The threshold setting module 601 of the control device 60 receives the gear signal of the stop cock valve 40 from the position sensor 50 and sets the flame threshold accordingly. The ignition control module 602 obtains the flame signal from the flame sensor 80 and the set flame threshold from the threshold setting module 601, and controls the ignition device 70 by comparing the flame signal with the flame threshold. In case a risk of leakage is detected, e.g. an accidental flame-out or a long time fire, the alarm module 603 outputs an alarm control signal to the alarm device. The valve control module 604 controls the energization or de-energization of the solenoid 400 of the plug valve 40 to open or close the plug valve 40.

Fig. 4 shows a perspective view of the plug valve 40 of the gas burner 1 from fig. 1 in different gears. In this exemplary embodiment and also referring to fig. 2, the plug valve 40 has, for example, six gears, namely a first gear to a sixth gear. Position sensor 50 detects the gear signal of plug valve 40 and control device 60 receives the gear signals of the different gears and sets the different flame thresholds accordingly. According to this embodiment, the first, second and third gears belong to the low gear and have a first flame threshold, the fourth, fifth and sixth gears belong to the high gear and have a second flame threshold, wherein the second flame threshold is greater than the first flame threshold.

As shown in fig. 4 (see also fig. 2), the left-hand stop cock 40 corresponds to the left-hand combustion device 20 in the figure and the stop cock 40 is currently in the high gear, for example the sixth gear. The right stop cock 40 corresponds to the right combustion device 20 and the stop cock 40 is currently in a low gear, for example the first gear. The control device 60 receives the signal of the position sensor 50 associated with the left-hand stop cock 40 and sets a second flame threshold value for this stop cock 40, and receives the signal of the position sensor 50 associated with the right-hand stop cock 40 and sets a first flame threshold value for this stop cock 40. Since the right plug valve 40 is in the first gear and the correspondingly set first flame threshold value is small, the flame detection value of the flame sensor 80 soon exceeds the first flame threshold value after ignition, so that the combustion device 20 is determined to have generated a flame and the ignition device 70 stops ignition (firing). This shortens the ignition duration, avoids long ignition times and thus reduces the ignition noise. In addition, the burner 20 is prevented from being erroneously determined to be extinguished. Correspondingly, the left-hand stop valve 40 is in the sixth gear and the correspondingly set second flame threshold is high. In this sixth gear, the plug valve 40 has a high opening, so that the gas supply is high and the corresponding combustion device 20 is associated with a high heating power. Since the second flame threshold is large, the flame detection value of the flame sensor 80 is quickly lower than the second flame threshold in the event of an accidental flameout of the combustion device 20. Accordingly, the control device 60 outputs a valve control signal to de-energize the solenoid of the stop cock valve 40, so that the stop cock valve 40 is closed. This has reduced the risk that the gas leaked effectively, has improved the safety in utilization.

Although specific embodiments have been described above, these embodiments are not intended to limit the scope of the disclosure, even if only a single embodiment is described with respect to a particular feature. The characteristic examples provided in the disclosure of the present application are intended to be illustrative, not limiting, unless stated differently. In the specific implementation, a plurality of features can be combined with each other according to actual needs, where technically feasible. Various substitutions, alterations, and modifications may be devised without departing from the spirit and scope of the present application.
