The ignition needle (1, 1 ') comprises electrodes (3, 3') and ceramic shells (2, 2 ') wrapped outside the electrodes, and is characterized in that electrode ignition direction limiting parts (4, 23') are arranged at the tops of the ceramic shells (2, 2 ') so as to limit the ignition direction of the electrodes (3, 3'), so that the ignition position and direction of the ignition needle can be realized according to specific design requirements, ignition action can be executed more accurately, and ignition efficiency is improved.
[ summary of the invention ]
An object of the present invention is to provide an improved burner of a gas range, a gas range including the same, and an ignition device of the gas range.
Another object of the present invention is to provide a burner of a gas range that protects an ignition needle when the burner is burning.
In one aspect, the embodiment of the invention relates to a burner of a gas stove, which comprises a burner body, an ignition device and a flame detection device, wherein the ignition device comprises an ignition needle with an ignition part, the ignition part is used for igniting gas, the ignition needle has a first position and a second position, when the flame detection device detects a flame signal of the burner body, the ignition needle is located at the first position, and the ignition part avoids flame; when the flame detection device does not detect the flame signal of the burner body, the ignition needle is located at the second position, and the ignition part is suitable for igniting the burner body.
The technical effect of above-mentioned scheme is embodied in that, when flame detection device detected the flame signal of combustor body, when the combustor burning promptly, the ignition needle was located the first position, and flame was avoided to the portion of igniteing. Therefore, the ignition needle can avoid the problem that the ignition part is difficult to ignite due to carbon deposition at the top end caused by long-term contact with flame. Meanwhile, the ignition part avoids flame, more space can be vacated, the combustion space can be increased, the secondary air circulation area is increased, and the fuel gas can be more sufficiently combusted. When the flame detection position does not detect the flame signal of the burner body, namely the burner is normally turned off or accidentally extinguished, the ignition needle is located at the second position, namely the ignition position, so that preparation is made for the next time of normal ignition or accidental extinguishment of the burner and then re-ignition is made.
On the other hand, in the burner body having the flame propagation groove, the presence of the ignition pin is also liable to interfere with the flame propagation to cause yellow flame contact. The yellow flame is clearly specified in the domestic gas cooker standard GB16410 to be impermissible, which also poses certain difficulties in the design of the burner. By adopting the technical scheme, the ignition needle moves to the first position to avoid flame when the combustor burns normally, so that the ignition needle avoids the problem of yellow flame contact caused by interference of flame.
It should be noted that "the ignition needle is located at the first position, and the ignition portion is away from the flame" includes at least two cases, but is not limited to: in one aspect, when the ignition needle is in the first position, the ignition portion is moved away from the flame zone such that the flame does not burn the ignition portion. Alternatively, when the ignition needle is in the first position, the ignition portion is located in a protective shield that covers the ignition portion from contact with the flame. Here, "the ignition portion is kept away from the flame" should be understood as meaning that the ignition portion does not contact the flame, that is, the flame does not burn into the ignition portion.
The ignition needle in the above scheme may be any one of a high-voltage pulse ignition needle or a hot-surface igniter which can be used for igniting gas. The ignition portion is, for example, an electrode head portion of an ignition needle for discharge.
The flame detection device in the above-described aspect may be any detection device that can be used to detect whether the flame of the burner body is burning or extinguished, such as a thermocouple or an ion flame detector.
In one or more embodiments, the ignition device further comprises a protective cover, and when the ignition needle is located at the first position, the ignition portion is located in the protective cover; when the ignition needle is located at the second position, the ignition part is exposed out of the protective cover.
The setting of safety cover can help the ignition portion to avoid contacting flame when combustor body burning on the one hand. For smaller burners or flat burners, it is not sufficient for the ignition to be able to shield the flame itself in the first position, but the protective cover can cover the ignition so that it is protected from the flame in the first position.
On the other hand, the ignition portion is arranged in the protective cover, so that the ignition portion can be protected, the ignition needle is prevented from being collided or damaged in the cooking process, and the service life of the ignition needle is prolonged.
In one or more embodiments, the ignition needle is elastically movable up and down in its axial direction so as to reach the first position and the second position.
In one or more embodiments, the ignition device includes a ferromagnetic member fixed to the ignition pin, a spring positioned between the ferromagnetic member and the electromagnet; when the electromagnet is electrified, magnetic attraction force is generated on the ferromagnetic part, and the ferromagnetic part drives the ignition needle to move to one of the first position and the second position; when the electromagnet is powered off, the magnetic attraction force on the ferromagnetic part disappears, and the ignition needle moves to the other one of the first position and the second position under the action of the restoring force of the spring. Wherein the ferromagnetic part is a ferromagnetic metal part. The movement of the ignition needle can be realized by electrifying and powering off the electromagnet, and the control is simple. When the electromagnet is electrified, the ferromagnetic part and the electromagnet are attracted to enable the ferromagnetic part to drive the ignition needle to move, and the spring is compressed at the moment; when the electromagnet is powered off, the ignition needle moves back to the original position under the action of the restoring force of the spring.
In one or more embodiments, the spring is sleeved on the ignition needle.
In one or more embodiments, the electromagnet is mounted on a fixed seat that is fixed to the burner body. Moreover, the fixing seat can also be used for fixing the ignition needle, so that the whole ignition device is assembled together, the fixing seat is well installed, and the ignition device is installed in place.
In one or more embodiments, the ignition device includes a limiting member for limiting the ignition needle to the second position, the ignition needle includes a flange matched with the limiting member, and the limiting member is fixed to the fixing base at an interval, or the limiting member is formed at the bottom of the protection cover. Therefore, the ignition position of the limit part for limiting the ignition needle accurately guarantees that the distance between the ignition part and the combustor body is the effective ignition distance, so that ignition can be successfully carried out.
In one or more embodiments, when the flame detection device detects a flame signal of the burner body, the electromagnet is electrified to generate a magnetic attraction force on the ferromagnetic piece, the ferromagnetic piece drives the ignition needle to move downwards to the first position, and the spring is compressed; when the flame detection device does not detect the flame signal of the burner body, the electromagnet is powered off and the magnetic attraction force to the ferromagnetic piece disappears, and the ignition needle moves upwards to the second position under the action of the restoring force of the spring. After the ignition needle moves down to first position, can vacate the space and give flame, consequently the combustion space of combustor body increases, and secondary air flow area increases, promotes the more abundant burning of gas, improves the burnout rate of gas. Moreover, the ignition needle moves down to a lower position of the burner, and the protection of the ignition needle itself is enhanced.
In one or more embodiments, the protective cover is directly or indirectly fixed to the burner body and/or at least the inner wall of the protective cover is made of an insulating material.
In one or more embodiments, the protective cover is an annular cover having openings in both the top and bottom. The ignition needle can thus run through the protective cap, so that the ignition section can be exposed outside the protective cap or located in the protective cap when the ignition needle is moved.
In another embodiment of the present invention, there is provided a gas range including the burner of the gas range according to any one of the above embodiments.
In one or more embodiments, the gas stove includes a control device, the ignition device and the flame detection device are respectively connected to the control device, and the control device is configured to control the ignition needle to be located at the first position or the second position according to whether the flame detection device detects a flame signal. When the combustor is ignited successfully and flame burns normally, the flame detection device detects a flame signal, and the control device transmits a corresponding command to the ignition device, so that the ignition needle moves to the first position, and the ignition part of the ignition needle leaves the flame and is hidden in the protective cover; when normally shutting off fire or accidentally extinguishing, the flame detection device cannot detect the flame signal, and the control device controls the ignition device to move the ignition needle to the second position through a program, and the ignition needle is located at the ignition position at the moment, so that the ignition part is suitable for igniting the burner body to prepare for next normal ignition.
In one or more embodiments, the ignition device is connected in series in a loop in which the flame detection device is located. Taking the flame detection device as an example of a thermocouple, when the flame is normally combusted, the thermocouple generates an electromotive force, and a current flows through a loop in which the thermocouple is located, so that the ignition device maintains the ignition needle at the first position. When the flame is extinguished, the temperature of the thermocouple is lower and lower, the electromotive force in the loop is gradually reduced until the current in the loop can not make the ignition device maintain the ignition needle at the first position, and the ignition needle automatically returns to the second position.
Another aspect of an embodiment of the present invention relates to an ignition device of a gas stove, which includes an ignition needle having an ignition portion for igniting gas, wherein the ignition needle has a first position and a second position in a use state of the gas stove; when the ignition needle is positioned at the first position, the ignition part avoids flame when the gas stove is burnt; when the ignition needle is located at the second position, the ignition part is suitable for igniting the gas stove.
Wherein, the 'using state of the gas stove' includes that the gas stove is in a burning state and the gas stove is in a closing state. It will also be understood that the gas burner is in use after it has been installed.
When the ignition needle is located at the second position, the ignition needle is located at the ignition position, and the ignition part can ignite the gas stove after the user gives an ignition instruction.
The ignition needle in the scheme can avoid flame when the gas stove burns, and the problem that the ignition part is not easy to ignite due to carbon deposition at the top end caused by long-term contact with the flame is avoided. Meanwhile, the ignition part avoids flame, more space can be vacated, the combustion space is increased, the secondary air circulation area is increased, and the gas of the gas stove is promoted to be more sufficiently combusted.
In one or more embodiments, the ignition device further comprises a protective cover, the ignition portion being located in the protective cover when the ignition needle is in the first position; when the ignition needle is located at the second position, the ignition part is exposed out of the protective cover.
In one or more embodiments, the ignition device includes a ferromagnetic member fixed to the ignition pin, a spring mounted on the burner body, and an electromagnet between the ferromagnetic member and the electromagnet; when the electromagnet is electrified, magnetic attraction force is generated on the ferromagnetic part, and the ferromagnetic part drives the ignition needle to move to one of the first position and the second position; when the electromagnet is powered off, the magnetic attraction force on the ferromagnetic part disappears, and the ignition needle moves to the other one of the first position and the second position under the action of the restoring force of the spring.
It should be pointed out that the features of the dependent claims can be combined with each other and with the features of the independent claims in any way without departing from the inventive concept.

[ detailed description ] embodiments
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
Referring to fig. 1 to 3, fig. 1 is a perspective view of a burner of a gas range according to an embodiment of the present invention; fig. 2 is a cross-sectional view of a burner of a gas range according to an embodiment of the present invention, when an ignition needle is located at a first position; fig. 3 is a cross-sectional view of a burner of a gas range according to an embodiment of the present invention, when an ignition needle is located at a second position.
The burner 1 of the gas range of the present embodiment includes a burner body 2, an ignition device 3, and a flame detection device 4.
The burner body 2 comprises a fire cover base 20, and an inner fire cover 21 and an outer fire cover 22 which are positioned on the fire cover base 20. The outer ring fire cover 22 is arranged around the outer periphery of the inner ring fire cover 21. The inner ring fire cover 21 and the outer ring fire cover 22 are both provided with a plurality of fire holes 200 for gas to flow out, and the gas flowing out from the fire holes 200 is ignited to form flame.
The ignition device 3 comprises an ignition needle 10 with an ignition portion 100, the ignition portion 100 being used for igniting the gas.
The ignition needle 10 of the present embodiment is a high-voltage pulse ignition needle, as shown in fig. 2, and includes an ignition electrode 101 and a ceramic case 102 wrapped outside the ignition electrode 101, and the top of the ignition electrode 101 is exposed outside the ceramic case 102 to form an ignition portion 100. During ignition, the ignition portion 100 generates an instantaneous high potential, and breaks down the air between the metals near the ignition hole 201 on the burner body 2 to form an electric spark, thereby igniting the gas ejected from the ignition hole 201.
The flame detection device 4 of the present embodiment is a thermocouple. The thermocouple and a solenoid valve (not shown) are connected in series to form a circuit for misfire protection. When the flame generated from the burner body 2 burns to the thermocouple, the thermocouple generates induced electromotive force, so that the opening of the solenoid valve can be maintained. When the flame of the burner body 2 is extinguished, the electromotive force of the thermocouple is rapidly reduced, and the opening of the electromagnetic valve cannot be maintained, so that the electromagnetic valve closes the gas.
The ignition needle 10 of the present embodiment has a first position and a second position. When the flame detection device 4 detects a flame signal from the burner body 2, the ignition needle 10 is located at the first position, and the ignition portion 100 avoids the flame, as shown in fig. 2, at this time, the ignition portion 100 is much lower than the ignition hole 201 and the ignition hole 200, and therefore, the flame burning in the ignition hole 200 and the ignition hole 201 does not contact the ignition portion 100. When the flame detection device 4 does not detect the flame signal of the burner body 2, the ignition needle 10 is located at the second position, and the ignition portion 100 is adapted to ignite the burner body 2. As shown in fig. 3, at this time, the ignition needle 10 is located at the ignition position, and the ignition portion 100 is aligned with the ignition hole 201, so that the ignition portion 100 is adapted to ignite the burner body 2, ready for ignition.
In addition, the ignition device 3 of the embodiment shown in fig. 1 further includes a protective cover 30, and when the ignition needle 10 is located at the first position, the ignition portion 100 is located in the protective cover 30, thereby further protecting the ignition portion 100 from the flame. When the ignition needle 10 is located at the second position, the ignition portion 100 is exposed outside the protective cover 30, and thus the ignition portion 100 is adapted to ignite the burner body 2.
In the embodiment shown in fig. 1, the protective cover 30 is fixed to the fire cover base 20 by a connecting portion 30 a. The protective cover 30 is an annular cover with an upper opening and a lower opening.
The protection cover 30 of the present embodiment is formed integrally with the fire lid base 20, and the protection cover 30 is made of aluminum or copper, which is the same material as the fire lid base 20. The inner wall of shield 30 is coated with an insulating layer, such as a ceramic polymer insulating coating, to prevent ignition needle 10 from being mishandled to discharge electricity toward the shield when in the first position.
The ignition device of the first embodiment will be described in detail below with reference to the accompanying drawings. Referring to fig. 4 to 6, fig. 4 is a perspective view of an ignition device according to a first embodiment of the present invention; fig. 5 is a front view of the ignition device of the first embodiment of the present invention with the ignition pin in the first position; fig. 6 is a front view of the ignition device of the first embodiment of the present invention with the ignition pin in the second position.
The ignition needle 10 of the present embodiment is elastically movable up and down in its axial direction so as to be able to reach the first position and the second position.
The ignition device 3 of the present embodiment further includes a ferromagnetic member 31, a spring 32, and an electromagnet 33. The ferromagnetic piece 31 may be made of a ferromagnetic metallic material. The ferromagnetic piece 31 of the present embodiment is a member made of iron. Ferromagnetic member 31 is fixed to ignition needle 10, and spring 32 is fitted over ignition needle 10 between ferromagnetic member 31 and electromagnet 33.
The electromagnet 33 is mounted on a fixed seat 34, and the fixed seat 34 is fixed on the burner body 2.
The ignition device 2 further includes a stopper 35 for restricting the ignition pin 10 to the second position. The limiting members 35 are fixed on the fixing base 34 at intervals by two connecting ribs 36. Ignition needle 10 includes a flange 110 for cooperating with retaining member 35 to retain ignition needle 10 in the second position.
As shown in fig. 5, when the flame detection device 4 detects a flame signal of the burner body 2, the electromagnet 33 is energized to generate a magnetic attraction force on the ferromagnetic member 31, the ferromagnetic member 31 drives the ignition needle 10 to move downward to the first position, and the spring 32 is compressed. Since the ignition needle 10 is moved down by a certain distance at this time, the ignition portion 100 is much lower than the flame to avoid the flame. As shown in fig. 6, when the flame detection device 4 does not detect the flame signal of the burner body 2, the electromagnet 33 is powered off and the magnetic attraction force to the ferromagnetic member 31 disappears, the ignition needle 10 moves upward under the restoring force of the spring 32 until the flange 110 abuts against the stopper 35, so that the ignition needle 10 is located at the second position, and at this time, the ignition portion 100 just faces the ignition hole 201, and is suitable for igniting the burner body 2.
The ignition device 3 of the present embodiment is connected in series to a circuit in which the flame detection device 4 is located in a use state. Thus, when the flame detection device 4 detects the flame signal of the burner body 2, the flame detection device 4, i.e. the thermocouple, generates an electromotive force, a current passes through a loop in which the flame detection device 4 is located, the electromagnet 33 is energized to generate a magnetic attraction force on the ferromagnetic member 31, the ferromagnetic member 31 drives the ignition needle 10 to move downward to the first position, and the spring 32 is compressed. When the flame is extinguished, the thermocouple temperature is lower and lower, the electromotive force in the circuit is gradually reduced until the current in the circuit makes the magnetic attraction of the electromagnet 33 to the ferromagnetic part 31 unable to maintain the ignition needle 10 at the first position, and under the restoring force of the spring 32, the ignition needle 10 automatically moves upwards and returns to the second position under the limit of the limit piece 35.
The same or similar structures in the ignition device of the first embodiment in the embodiments shown in fig. 2 and fig. 3 are the same in reference numerals, and the functions and functions thereof are the same, and are not described again.
Next, an ignition device according to a second embodiment of the present invention will be described. Referring to fig. 7 and 8, fig. 7 is a perspective view of an ignition device according to a second embodiment of the present invention; fig. 8 is a partially enlarged sectional view of an ignition device according to a second embodiment of the present invention.
The same or similar structures of the ignition device in the second embodiment and the first embodiment are labeled with the same symbols, and the functions thereof are the same or similar, and are not repeated herein, please refer to the previous description. Unlike the first embodiment, the stopper 35 of the present embodiment is formed at the bottom of the protection cap 30. The protective cover 30 has openings at both the top and bottom, but the bottom opening is smaller than the top opening. The edge of the opening at the bottom of the protective cover 30 forms a stopper 35. Ignition needle 10 moves upward under the restoring force of spring 32 until flange 110 of ignition needle 10 abuts against stop 35, thereby limiting ignition needle 10 to the second position.
Of course, the protective cover 30 of the present embodiment is to be fixed, but is not shown in fig. 7 and 8. In practice, the protective cover 30 can be fixed on the fire cover base 20 or on the bottom shell of the gas stove. The protective cover 30 of the present embodiment is made of ceramic.

In one embodiment, the gas stove further comprises a control device, the ignition device 3 and the flame detection device 4 are respectively connected with the control device, and the control device is used for controlling the ignition needle 10 to be located at the first position or the second position according to whether the flame detection device 4 detects a flame signal. The control device is preset with a relevant program, and controls the ignition needle 10 to be positioned at the first position when the flame detection device 4 detects a flame signal of the burner body 2 through program control; when the flame detection device 4 does not detect the flame signal of the burner body 2, the ignition needle 10 is controlled to be located at the second position.
Still other embodiments of the present invention provide an ignition device 3 of a gas range, which includes an ignition needle 10 having an ignition portion 100, the ignition portion 100 being used to ignite gas. The ignition needle 10 has a first position and a second position in the use state of the gas range. When the ignition needle 10 is located at the first position, the ignition portion 100 avoids flames when the gas range is burned. The ignition portion 100 is adapted to ignite the gas range when the ignition needle 10 is located at the second position.
In one embodiment, the ignition device 3 further includes a protective cover 30, and the ignition portion 100 is located in the protective cover 30 when the ignition needle 10 is located at the first position; when the ignition needle 10 is located at the second position, the ignition portion 100 is exposed to the outside of the protection cover 30.
The ignition device 3 includes a ferromagnetic member 31, a spring 32, and an electromagnet 33, the ferromagnetic member 31 is fixed to the ignition needle 10, and the spring 32 is fitted over the ignition needle 10 and located between the ferromagnetic member 31 and the electromagnet 33.
