Description

Electric hybrid gas stove

Technical Field

The application relates to the technical field of smart homes, in particular to an electric hybrid gas stove.

Background

The traditional gas stove realizes heating a cooker above the combustion device by guiding gas in a municipal gas pipeline or a gas storage tank into the combustion device and burning the gas on the combustion device. The flame size generated by the gas in the combustion process can be adjusted by a flame adjusting knob on the pipeline in the gas stove. I.e., adjusting the valve opening of the flame adjustment knob so as to adjust the flow of gas into the combustion device. Generally, the gas supply pressure in the municipal gas pipeline or the gas storage tank is constant, so that the flame on the combustion device can be maintained in a stable state without changing the flame adjusting knob.

However, if the gas supply is abnormal, such as when the gas supply is stopped by an accident in a municipal gas pipeline or when the gas in the gas storage tank is about to be exhausted, the amount of the gas introduced into the combustion device may fluctuate abnormally. In this case, not only the flame stability on the burner is impaired, but also, in the event of sudden fluctuations in the gas pressure, the flame on the burner is extinguished. If the cooking state is being performed, the normal cooking process is terminated. In addition, because the flame adjusting knob is in an opening state in the cooking state, gas can still be supplied to the combustion device after the flame is extinguished. The supplied gas can be emitted to the indoor environment without burning, thereby threatening the personal safety and having larger fire hazard.

In order to avoid gas leakage into the indoor environment, a gas detection sensor and a controller corresponding to the gas detection sensor can be arranged in the gas stove. In practical application, if the flame on the combustion device is extinguished and there is gas leakage, the gas detection sensor will detect the gas leakage and send the detected signal to the control. After receiving the detection signal, the controller can control the electromagnetic valve on the gas pipeline to be closed in time, or control the alarm device to send out an acousto-optic signal to prompt an operator to close the flame adjusting knob.

However, the gas range with the gas detection sensor can only prevent the gas from being emitted into the indoor space by shutting off the gas supply in practical use, which results in that the interrupted cooking process cannot be recovered. Moreover, the fluctuation in the municipal gas pipeline or the gas storage tank is unpredictable, and may be continuous in some cases, so that the conventional gas cooker cannot finish cooking when the gas supply fluctuates.

Detailed Description

Referring to fig. 1, a schematic structural diagram of an electric hybrid gas cooker according to the present application is shown.

The application provides an electric hybrid gas stove includes: the device comprises a platform 1, a combustion device 2, an air supply pipeline 3, a regulating device 4, a control system 5 and an electric heating system 6. The platform 1 is used for mounting and fixing other components and realizing separation between the working plane of the gas stove and the internal components. In practical application, a smooth platform surface is maintained above the platform 1, and at least one combustion hole 11 is arranged; ignition and combustion components such as a gas pipeline, a furnace end and the like are arranged below the platform 1. For example, the combustion hole 11 may be a circular through-hole structure opened on the platform 1.

And the combustion device 2 is arranged in the combustion hole 11 on the platform 1 and used for combusting gas and heating the pot 7 above. In practical applications, the combustion device 2 may include a combustion furnace 21, and the combustion furnace 21 is connected to the air supply pipeline 3 through a gas pipeline. The burner 21 has a porous structure so that the gas in the gas supply line 3 can be introduced into the burner 21 and released in the porous structure of the burner 21. The combustion device 2 may further include an igniter, which may be a structure such as a discharge needle capable of generating an electric spark, to ignite the gas released from the porous structure by the igniter, thereby forming a stable flame above the combustion device 2.

As shown in fig. 2, the gas supply line 3 is disposed below the platform 1 and communicates with the combustion device 2 to supply gas to the combustion device 2. In the technical scheme provided by the application, the gas supply pipeline 3 can comprise two types, one type is a gas pipeline arranged inside the gas stove, and the other type is a joint pipeline arranged outside the gas stove. The joint pipeline can be made of metal pipes so as to improve the stability of the joint pipeline and a municipal gas supply pipeline or a gas tank; the gas pipe can be made of soft plastic pipe to facilitate the flexible arrangement of the pipe and the adjustment of the position of the burner 21.

And an adjusting device 4 provided on the gas supply line 3 to adjust the flow rate of the gas supplied to the combustion device 2. In practical applications, the adjusting device 4 can adjust the flame size of the combustion device 2 by adjusting the flame adjusting knob 41 or the control valve provided on the gas supply line 3 to adjust the pressure of the supplied gas. It should be noted that, in the technical solution provided in the present application, the adjusting device 4 may also adjust the on-off state of the air supply line 3 through a control valve, such as an electromagnetic valve. For example, when the supply of gas is abnormal, the controller 52 controls the electromagnetic valve to close, and the gas supply of the combustion device 2 is stopped, thereby preventing the gas from leaking into the space environment.

The control system 5 includes a pressure sensor 51 and a controller 52. Wherein, a pressure sensor 51 is arranged in the gas supply pipeline 3, and a controller 52 is connected with the pressure sensor 51 to obtain the gas pressure in the gas supply pipeline 3. In the present application, the pressure sensor 51 can detect the gas pressure in the gas supply line 3 in real time, and can be a micro pressure gauge, so as to convert the gas pressure in the gas supply line 3 into an electric signal and transmit the electric signal to the controller 52. The controller 52 may be a processor device built in the lower portion of the gas range platform 1, and the controller 52 may simply make a judgment according to signals detected by the sensors connected thereto, and make a corresponding control instruction according to a preset control program. Thus, the controller 52 may be a microprocessor, a single chip, a programmable logic controller, or the like.

In the technical scheme provided by the application, the controller 52 automatically judges whether the gas supply is abnormal or not by receiving the gas pressure data detected by the pressure sensor 51. In a specific determination manner, assuming that the gas supply pressure in the gas supply line 3 is M without an abnormal condition, and the allowable abnormal fluctuation coefficient is 0.2 according to the specific structure of the combustion furnace 21, in practical application, if the gas pressure value detected by the pressure sensor 51 is lower than (1-0.2) M within a preset time interval, it is determined that the gas pressure value is too low, that is, the gas supply fluctuation occurs. It should be understood that the allowable range of the supply pressure fluctuation differs for different types of structures of the combustion furnace 21, and therefore, the abnormal fluctuation coefficient can be determined by a reliability test in practical use. The above-described abnormality determination process may be implemented by a program built in the controller 52.

And the electric heating system 6 is arranged below the combustion hole 11 side of the platform 1. In the technical scheme provided by the application, the electric heating system 6 heats the pot 7 in an electric heating mode, and the specific heating element can be an electric heating wire or an electromagnetic coil. But for convenience of use, the heating element is preferably a heating wire in the present application. Thus, the electric heating system 6 includes the electric heating plate 61 and the slide mechanism 62. Wherein, electric plate 61 can be the platelike structure of inside encapsulation heating wire, and when practical application, electric plate 61 can contact the bottom of pan 7 to give pan 7 with the heat transfer that the electric current produced, in order to cook. The electric heating plate 61 also supports the pot 7, and therefore, the electric heating plate 61 should have a certain thickness to be able to bear the weight of the pot 7 and the food material contained therein. The sliding mechanism 62 is connected with the electric heating plate 61 to drive the electric heating plate 61 to slide above the combustion hole 11; the controller 52 is connected to the slide mechanism 62 to control the movement of the slide mechanism 62 in accordance with the gas pressure in the gas supply line 3.

According to the technical scheme, the electric hybrid gas stove provided by the application can detect the gas supply pressure in the gas supply pipeline 3 in real time through the pressure sensor 51, and send the detected pressure value to the controller 52, and the controller 52 determines whether the abnormal fluctuation occurs in the gas supply pipeline 3 according to the received pressure value. If the supply pressure is kept stable, determining that no abnormal fluctuation exists in the current air supply pipeline 3, and then keeping a normal cooking state; if the supply pressure is unstable, it is determined that the current air supply pipeline 3 has abnormal fluctuation, and the fluctuation at this time easily causes the flame on the combustion device 2 to be extinguished, so the controller 52 can close the air supply pipeline 3, and control the sliding mechanism 62 to move, drive the electric heating plate 61 to cover the combustion hole 11 and contact the bottom of the pot 7, and continue to heat the pot 7.

For better continuation of the cooking process, as shown in fig. 3, in some embodiments of the present application, the adjusting means 4 comprises a flame adjustment knob 41 and an angle sensor 42 connected to the flame adjustment knob 41. The angle sensor 42 may detect the current angle of the flame adjustment knob 41 by connecting a rotation shaft of the flame adjustment knob 41. Therefore, the angle sensor 42 may be a hall element, a resistance sensor, a grating sensor, or the like capable of measuring the rotation angle.

The flame adjustment knob 41 is provided on the air supply line 3, and the controller 52 is connected to the angle sensor 42 to detect the angle of the flame adjustment knob 41. The controller 52 is also connected to the electric heating plate 61 to control the heating power of the electric heating plate 61 according to the angle of the flame adjustment knob 41. In practical applications, since the flame adjustment knob 41 can adjust the flow of the gas entering the combustion device 2, the rotation angle of the flame adjustment knob 41 corresponds to a kind of fire. In order to make the cooking process more smooth, a control program may be built in the controller 52 to correspond the heating power of the electric heating plate 61 to the gas flow rate of the combustion device 2, i.e., to the rotation angle of the flame adjustment knob 41, so that after the gas heating is switched to the electric heating, the duration of the heat before and after the switching is maintained, thereby maintaining the normal cooking process.

In some embodiments of the present application, the combustion device 2 includes a combustion furnace 21 and a lifting mechanism 22 disposed below the combustion furnace 21. The combustion furnace 21 is connected to the gas supply line 3, and the controller 52 is connected to the elevating mechanism 22 to control the height of the combustion furnace 21 according to the gas pressure in the gas supply line 3.

In practical application, according to different gas stove structures, the arrangement heights of the combustion devices 2 are different, for example, the combustion devices 2 of some gas stoves are completely arranged below the platform 1, the combustion devices 2 do not protrude out of the platform 1 due to the structure, an electric heating system 6 can be conveniently and directly arranged at the bottom of the platform 1, but the combustion holes 11 limit the air flow of a combustion space part, so that the oxygen amount participating in combustion on the combustion devices 2 is limited, and the full combustion is not facilitated. In order to sufficiently burn, the combustion device 2 of some gas cookers protrudes from the combustion hole 11, and with the gas cookers of this structure, the protrusion of the combustion device 2 may hinder the arrangement and moving process of the electric heating plate 61. Therefore, the height of the combustion apparatus 2 can be adjusted by providing the lifting mechanism 22 at the bottom of the combustion apparatus 2.

In the embodiment, the height of the combustion device 2 can be adjusted through the lifting mechanism 22, on one hand, when the air supply pressure is reduced, the flame can contact the bottom of the cooker 7 through increasing the combustion device 2, so as to maintain the normal operation of the cooking process; on the other hand, after the gas supply of the combustion device 2 is stopped, the combustion device 2 may be turned down so that the entire combustion device 2 is located below the platform 1, thereby preventing the combustion device 2 from blocking the movement of the electric heating plate 61.

Further, as shown in fig. 4, the elevating mechanism 22 includes a driving motor 23, a transmission gear set 24, a transmission thread bush 25, and an elevating wheel disc 26. The lifting wheel disc 26 is fixedly connected to the bottom of the combustion furnace 21; the transmission thread bush 25 is sleeved on the lifting wheel disc 26 through thread transmission; gear teeth are arranged on the outer wall of the transmission threaded sleeve 25 and are connected with the transmission gear set 24 through the gear teeth; the transmission gear set 24 is connected with a driving motor 23.

In practical applications, as shown in fig. 4 and 5, the driving motor 23 is connected to the controller 52 to control the on time and the number of turns of the driving motor 23 through the controller 52. For this, the driving motor 23 may be a stepping motor, a servo motor, or the like disposed under the stage 1. The transmission gear set 24 converts the rotation speed of the driving motor 23 to output proper rotation speed and torque to maintain the stability of the lifting process. The drive screw 25 and the lifting wheel 26 are adapted to transmit the rotation transmitted by the drive gear set 24 into a movement of the lifting wheel 26 by means of a screw drive.

In practical application, if the combustion device 2 protrudes from the platform 1 during cooking, the pot 7 can be placed above the combustion device 2 through the supporting component. The electric heating plate 61 needs to contact the bottom of the pot 7 during the heat transfer process, so in some embodiments of the present application, the combustion apparatus 2 further includes a supporting member 27 penetrating through the platform 1, and the supporting member 27 may be a trapezoidal sheet structure or an L-shaped strip structure for supporting the pot 7. The supporting member 27 is fixed to the side wall of the burner 21, and the height of the pot 7 is adjusted in accordance with the movement of the burner 21. In this embodiment, as the height of the supporting member 27 is lowered, the height of the pot 7 is gradually lowered so that the bottom surface of the pot 7 can contact the electric heating plate 61.

In practical use, in order to ensure that the height of the combustion apparatus 2 is lowered, the electric heating plate 61 supports the pot 7, so that the electric heating plate 61 and the combustion apparatus 2 can move simultaneously by the interlocking member as shown in fig. 6 and 7. Specifically, the sliding mechanism 62 includes a slider 63 and a linkage rod 64. The sliding block 63 is fixedly connected with the bottom surface of the electric heating plate 61, one end of the linkage rod 64 is hinged with the sliding block 63, and the other end is hinged with the side wall of the combustion furnace 21. The present embodiment realizes simultaneous movement in a mechanical linkage manner through the linkage rod 64, and has a simple structure and does not need redundant program control.

In addition, in the technical scheme provided by the application, the movement of the electric heating plate 61 and the linkage between the electric heating plate 61 and the combustion device 2 can also be realized in an electromagnetic driving mode. Namely, the sliding mechanism 62 is a piston rod provided on the bottom surface of the platform 1; the movable end of the piston push rod is fixedly connected with the side surface or the bottom surface of the electric heating plate 61. In practical applications, the electric heating plate 61 may be disposed in a predetermined slide way to perform guiding and supporting functions. The piston rod can be an electromagnetic or transmission structure to realize the pushing and pulling action on the electric heating plate 61.

In order to realize the linkage between the electric heating plate 61 and the combustion device 2, a corresponding control program may be preset in the controller 52, so that the starting timings of the sliding mechanism 62 and the lifting mechanism 22 are the same, and the operating speed thereof may be further controlled to obtain a stable motion state.

In practical application, the electric heating plate 61 needs to contact with the bottom surface of the pot 7 to effectively transfer heat. And for the gas heating mode, the pot 7 can be a pan or a round-bottom pot. Wherein, the pan can be directly contacted with the electric heating plate 61, while the round-bottomed pan can not be well contacted with the electric heating plate 61, if the same control mode is still adopted, not only the heat transfer is influenced, but also the cooker 7 can be overturned. Therefore, in order to adapt to the round bottom pan condition, as shown in fig. 8, in some embodiments of the present application, the control system 5 further includes an image collector 53 and an alarm device 54.

Wherein, the image collector 53 is arranged at the side wall position of the combustion hole 11, and the controller 52 is connected with the image collector 53 to obtain the shape of the pot 7; the controller 52 is further connected to an alarm device 54 to control the alarm device 54 to generate an alarm signal when the pot 7 is a round-bottomed pot. It should be noted that, in order to adapt to the shape of the round-bottomed pot, the present application may further adopt a concave electric heating plate to fit the bottom surface of the round-bottomed pot, so that the pot 7 can be stably placed on the electric heating plate 61.

In some embodiments of the present application, at least two electric heating plates 61 are disposed below each of the combustion holes 11 of the gas range. Each electric heating plate 61 is connected with a sliding mechanism 62, so that each sliding mechanism 62 drives the electric heating plate 61 to move independently. The plurality of electric heating plates 61 corresponding to the same combustion hole 11 have a structure of being spliced with each other to close the combustion hole 11. In this embodiment, the combustion holes 11 can be covered by a plurality of electric heating plates 61, for example, one combustion hole 11 corresponds to two electric heating plates 61, and then the two electric heating plates 61 can be rectangular or semicircular; for another example, if one combustion hole 11 corresponds to three electric heating plates 61, the three electric heating plates 61 may have a sector structure of 1/3 circles.

Further, the combustion holes 11 are cylindrical hole-shaped structures, and each combustion hole 11 corresponds to two semicircular electric heating plates 61; the straight side surfaces of the two electric heating plates 61 are provided with concave-convex splicing structures which are matched with each other. In practical application, the concave-convex splicing structure can support the two electric heating plates 61 mutually to support the cookware 7 above together. Specifically, the straight side surface of one electric heating plate 61 is provided with a groove, and the straight side surface of the other electric heating plate 61 is provided with a protrusion matched with the groove, so that mutual support is realized through the matching of the protrusion and the groove.

According to the technical scheme, the electric hybrid gas stove can provide two gas heating modes and two electric heating modes, can automatically judge whether the gas supply state is abnormal or not through the pressure sensor 51 and the controller 52, and can automatically switch to the electric heating mode when the gas supply state is abnormal.
