[0002] The gas oven with timing control, as an advanced technology in modern kitchen equipment, integrates a high-precision time control system and an intelligent gas regulation mechanism. The gas oven with timing control allows users to preset the cooking time, precisely control the opening and closing of the gas supply and the automatic adjustment of the firepower size through a built-in microprocessor, so as to ensure that the ingredients are evenly heated within the set time period and achieve an ideal cooking effect. This kind of gas oven not only simplifies the cooking process, improves the cooking accuracy and efficiency, but also brings great convenience to users, and is an indispensable cooking tool in modern family and commercial kitchens.

[0003] In the existing timing gas oven technology, in order to improve the cooking convenience and automation level, a timer is generally used to control the opening and closing of the gas valve. This setting allows users to stably supply gas to the burner mechanism to maintain the flame combustion by keeping the gas valve open within the preset time period, realizing an unattended cooking process. However, during the operation, if the burner mechanism accidentally goes out due to various reasons such as gas pressure fluctuations, burner blockages, wind force effects, etc., the gas will keep leaking, thus there is a safety hazard, endangering personal and property safety.

[0004] The present utility model is studied and proposed in view of the deficiencies of the existing technology. Content of the Utility Model

[0005] In view of the problem that the existing timing gas oven uses a timer to control the opening and closing of the gas valve, and if the burner mechanism accidentally goes out when the gas valve remains open, it will cause the gas to keep leaking, thus there is a safety hazard, endangering personal and property safety, the technical solution adopted by the present utility model to solve its technical problems is as follows:

[0006] The gas oven with timing control includes an oven body, on which a timing control component, a gas valve component electrically connected to the timing control component, and a baking cavity are provided. A burner component connected to the gas valve component is provided on the baking cavity, and a flameout sensor electrically connected to the timing control component is provided on one side of the burner component.

[0007] Furthermore, a power terminal component connected to the timing control component is provided on the oven body.

[0008] Furthermore, a thermostat electrically connected to the timing control component is provided on the oven body.

[0009] Further, the burner assembly includes a first burner assembly located at the upper part of the baking chamber and a second burner assembly located at the bottom of the baking chamber. The gas valve assembly includes an upper gas pipeline assembly communicated with the first burner assembly and a lower gas pipeline assembly communicated with the second burner assembly.

[0010] Further, the first burner assembly includes a first gas burner mechanism and a first ignition mechanism for igniting the first gas burner mechanism. The upper gas pipeline assembly includes a first upper gas pipeline communicated with the first gas burner mechanism and a second upper gas pipeline communicated with the first ignition mechanism.

[0011] Further, the first ignition mechanism includes a first ignition bracket located on one side of the first gas burner mechanism, a first ignition gas outlet pipe and a first ignition element respectively located on the first ignition bracket. The first ignition gas outlet pipe is provided with a first gas outlet on the side facing the first gas burner mechanism. The first ignition element is located on one side of the first ignition gas outlet pipe and can ignite the gas output from the first gas outlet. The flameout inductor includes a first flameout inductor located on the first ignition bracket near the first gas outlet.

[0012] Further, a plurality of first gas outlets are arranged along the axial direction of the first gas burner mechanism. The first burner assembly further includes a first heat reflecting plate connected to the first gas burner mechanism and located above the first gas outlet.

[0013] Further, a plurality of heat transfer ports communicated with the second burner assembly are provided at the bottom of the baking chamber.

[0014] Further, the flameout inductor is a thermocouple.

[0015] Further, an installation rack is provided on the oven body above the baking chamber. The timing control assembly and the gas valve assembly are both arranged on the installation rack.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. In the present utility model, a flameout inductor is arranged on one side of the burner assembly, and the flameout inductor is electrically connected to the timing control assembly. Under normal conditions, the timing control assembly controls the opening and closing of the gas valve assembly, so that the gas valve assembly can stably supply gas for combustion to the burner assembly. When the burner assembly accidentally flames out, the flameout inductor can sense the flameout state of the burner assembly, and the flameout inductor sends an electrical signal to the timing control assembly, and the timing control assembly closes the gas valve assembly, effectively solving the problem that the existing timed gas oven uses a timer to control the opening and closing of the gas valve. When the gas valve remains open, if the burner mechanism accidentally flames out, it will cause the gas to leak continuously, thus posing a safety hazard and endangering personal and property safety;

[0018] 2. By setting the timing control assembly, users can preset the cooking time to achieve automatic operation of the oven. Within the preset time, the oven will automatically control the opening and closing of the gas valve assembly and monitor the combustion state of the burner assembly through the flameout inductor, so that the baking process does not require manual intervention, greatly improving the convenience of cooking.

[0027] The following will describe in detail the embodiments of the present utility model in conjunction with the drawings.

[0028] As Figures 1 to 7The shown gas oven with timing control includes an oven body 1, on which a timing control component 2, a gas valve component 3 electrically connected to the timing control component 2, and a baking chamber 4 are provided. On the baking chamber 4, a burner assembly 5 connected to the gas valve component 3 is provided. On one side of the burner assembly 5, a flameout inductor 7 electrically connected to the timing control component 2 is provided;

[0029] In the utility model, by arranging a flameout inductor on one side of the burner assembly, the flameout inductor is electrically connected to the timing control component. Under normal conditions, the timing control component controls the opening and closing of the gas valve component so that the gas valve component can stably supply gas for combustion to the burner assembly. When the burner assembly accidentally goes out, the flameout inductor can sense the flameout state of the burner assembly, and the flameout inductor sends an electrical signal to the timing control component, and the timing control component closes the gas valve component, effectively solving the problem that the existing timed gas oven uses a timer to control the opening and closing of the gas valve. When the gas valve remains in the open state, if the burner mechanism accidentally goes out, it will cause the gas to leak continuously, thus there is a potential safety hazard, endangering personal and property safety.

[0030] Furthermore, by arranging the timing control component 2, the user can preset the cooking time to realize the automatic operation of the oven. Within the preset time, the oven will automatically control the opening and closing of the gas valve component 3, and monitor the combustion state of the burner assembly 5 through the flameout inductor 7, so that the baking process does not require manual intervention, greatly improving the convenience of cooking.

[0031] Optionally, in some embodiments, the flameout inductor 7 can be an ion induction type inductor.

[0032] Optionally, in some embodiments, the flameout inductor 7 can be a photoelectric type inductor.

[0033] Optionally, in some embodiments, the flameout inductor 7 can be a thermal type inductor.

[0034] Furthermore, as a preferred mode rather than a limitation of the utility model, the flameout inductor 7 is a thermocouple. The working mode of the thermocouple is that it can be directly in contact with the monitored flame, so it can more directly sense the temperature change of the flame. This setting enables the thermocouple to provide more accurate flame state information, thus ensuring the accuracy of flameout protection; secondly, the material of the thermocouple is usually selected from high-temperature resistant and corrosion-resistant metals, such as platinum, rhodium, etc. These metals have good physical and chemical properties and can resist the high temperature and corrosive environment during gas combustion, thus effectively extending the service life of the thermocouple.

[0035] As Figures 1 to 7 On the shown oven body 1, a power terminal component 11 connected to the timing control component 2 is provided;

[0036] Specifically, the timing control component 2 is connected to the power terminal component 11. After the external power supply is cut off, the timing control component 2 stops working, so that the flameout inductor 7 cannot transmit a signal to the gas valve component 3 through the timing control component 2. The gas valve component 3 cannot receive the signal and then closes the gas valve to stop the gas transmission, effectively avoiding continuous gas leakage caused by power interruption, thereby reducing the risks of fire and explosion.

[0037] As Figures 1 to 7 shown, a thermostat 12 electrically connected to the timing control component 2 is provided on the oven body 1;

[0038] Specifically, the thermostat 12 is electrically connected to a temperature sensing probe provided in the baking cavity 4 to be able to detect the internal temperature of the baking cavity 4. The thermostat 12 is electrically connected to the timing control component 2. When the thermostat 12 senses through the temperature sensing probe that the internal temperature of the baking cavity 4 is too high, the thermostat 12 controls the timing control component 2 to disconnect, so that the flameout inductor 7 cannot transmit a signal to the gas valve component 3 through the timing control component 2. The gas valve component 3 cannot receive the signal and then closes the gas valve to stop the gas transmission, effectively preventing fires or equipment damage caused by too high internal temperature in the baking cavity 4 and greatly enhancing the safety of use.

[0039] Optionally, in some embodiments, the thermostat 12 is a digital thermostat.

[0040] Optionally, in some embodiments, the thermostat 12 is an electronic thermostat.

[0041] Further, as a preferred but non-limiting manner of the present invention, the thermostat 12 is a snap-action thermostat.

[0042] As Figures 1 to 7 shown, the burner assembly 5 includes a first burner assembly 51 located above the baking cavity 4 and a second burner assembly 52 located at the bottom of the baking cavity 4. The gas valve assembly 3 includes an upper gas pipeline assembly 31 communicating with the first burner assembly 51 and a lower gas pipeline assembly 32 communicating with the second burner assembly 52;

[0043] Further, by providing the first burner assembly 51 and the second burner assembly 52, the user can select the first burner assembly 51 or the second burner assembly 52 according to actual needs, can more flexibly control the temperature distribution in the baking cavity 4, is beneficial to increasing various baking modes and functions, and effectively improves the practicality of the oven.

[0044] Optionally, in some embodiments, both the first burner assembly 51 and the second burner assembly 52 are located above the baking cavity 4.

[0045] Optionally, in some embodiments, both the first burner assembly 51 and the second burner assembly 52 are located at the bottom of the baking chamber 4.

[0046] Optionally, in some other embodiments, the first burner assembly 51 and the second burner assembly 52 can also be located on the left and right sides of the baking chamber 4 respectively.

[0047] Furthermore, as a preferred embodiment of the present invention rather than a limitation, the first burner assembly 51 is located above the baking chamber 4, and the second burner assembly 52 is located at the bottom of the baking chamber 4. By the simultaneous action of the upper and lower burner assemblies, the heat in the baking chamber 4 can be distributed in multiple directions, which is beneficial to making the heat act on the food more evenly, helping to improve the baking effect, so that the food is heated more evenly and avoiding the occurrence of local overheating or undercooking.

[0048] As Figures 1 to 7 shown, the first burner assembly 51 includes a first gas burner mechanism 511 and a first ignition mechanism 512 for igniting the first gas burner mechanism 511. The upper gas pipeline assembly 31 includes a first upper gas pipeline 311 communicating with the first gas burner mechanism 511 and a second upper gas pipeline 312 communicating with the first ignition mechanism 512;

[0049] Furthermore, when the gas valve assembly 3 controls the first burner assembly 51 to supply gas, through the continuous combustion of the first ignition mechanism 512, the first gas burner mechanism 511 can be re-ignited when the first gas burner mechanism 511 suddenly goes out, preventing the gas leakage of the first gas burner mechanism 511; secondly, the way the first ignition mechanism 512 ignites the first gas burner mechanism 511 is to first ignite the first ignition mechanism 512 and then supply gas to the first gas burner mechanism 511 to ignite the first gas burner mechanism 511. In this way, during the process of igniting the first burner assembly 51, even if there are problems when initially igniting the first ignition mechanism 512 and it is not easy to ignite, the gas leakage amount of the first ignition mechanism 512 is less, which is beneficial to improving safety.

[0050] Furthermore, the second upper gas pipeline 312 specifically supplies gas to the first ignition mechanism 512, and the first upper gas pipeline 311 communicates with the first gas burner mechanism 511. This split pipeline setting makes the gas supply more accurate, which is beneficial to ensuring that the first ignition mechanism 512 and the first gas burner mechanism 511 can obtain sufficient gas during their respective working stages, thereby improving the ignition efficiency and combustion stability.

[0051] As Figures 1 to 7The first ignition mechanism 512 shown includes a first ignition bracket 5121 located on one side of the first gas burner mechanism 511, a first ignition gas outlet pipe 5122 and a first ignition element 5123 respectively located on the first ignition bracket 5121. The first ignition gas outlet pipe 5122 is provided with a first gas outlet 5124 on the side facing the first gas burner mechanism 511. The first ignition element 5123 is located on one side of the first ignition gas outlet pipe 5122 and can ignite the gas output from the first gas outlet 5124. The flameout inductor 7 includes a first flameout inductor 71 located on the side of the first ignition bracket 5121 close to the first gas outlet 5124;

[0052] Further, by providing the first ignition bracket 5121, the first ignition gas outlet pipe 5122, the first ignition element 5123 and the first flameout inductor 71 can be integrated on the first ignition bracket 5121, so that the structure of the first ignition mechanism 512 is compact and orderly, which is beneficial to reducing the space occupation and improving the overall integration degree of the device.

[0053] Further, the first ignition gas outlet pipe 5122 and the first ignition element 5123 are respectively installed on the first ignition bracket 5121, and the first gas outlet 5124 faces the first gas burner mechanism 511, effectively ensuring that the gas on the first ignition gas outlet pipe 5122 can be accurately ignited and the flame can be effectively transmitted to the first gas burner mechanism 511.

[0054] Further, the first flameout inductor 71 is located on the side of the first ignition bracket 5121 close to the first gas outlet 5124. Such a position setting enables the first flameout inductor 71 to quickly detect the change of the flame state, which is beneficial to improving the response speed of the first flameout inductor 71.

[0055] As Figures 1 to 7 The first gas burner mechanism 511 shown is provided with a plurality of first gas outlets 5111 distributed along its axial direction. The first burner assembly 51 further includes a first heat reflecting plate 53 connected to the first gas burner mechanism 511 and located above the first gas outlets 5111;

[0056] Further, the first heat reflecting plate 53 can reflect the thermal radiation and waste heat ejected from the first gas outlets 5111 and guide them towards the bottom of the baking cavity 4. Such a setting not only reduces the heat loss, but also makes the heat act more concentratedly in the baking cavity 4, thus significantly improving the thermal efficiency of the oven body 1.

[0057] Further, through the reflection and diffusion of the first heat reflecting plate 53, the flame and heat are more evenly distributed in the baking cavity 4, which helps to avoid the problems of local overheating or uneven heating and is beneficial to improving the cooking effect.

[0058] As Figures 1 to 7 shown, a plurality of heat transfer ports 41 communicating with the second burner assembly 52 are provided at the bottom of the baking chamber 4;

[0059] Specifically, the structure of the second burner assembly 52 corresponds to that of the first burner assembly 51, and the working process of the second burner assembly 52 is the same as that of the first burner assembly 51.

[0060] Furthermore, the second burner assembly 52 includes a second gas burner mechanism 521 and a second ignition mechanism 522 for igniting the second gas burner mechanism 521. The lower gas pipeline assembly 32 includes a first lower gas pipeline 321 communicating with the second gas burner mechanism 521 and a second lower gas pipeline 322 communicating with the second ignition mechanism 522.

[0061] Furthermore, the second ignition mechanism 522 includes a first ignition bracket 5221 located on one side of the second gas burner mechanism 521, a second ignition outlet pipe 5222 and a second ignition element 5223 respectively located on the first ignition bracket 5221. A second air outlet 5224 is provided on the side of the second ignition outlet pipe 5222 facing the second gas burner mechanism 521. The second ignition element 5223 is located on one side of the second ignition outlet pipe 5222 and can ignite the gas output from the second air outlet 5224. The flameout inductor 7 includes a second flameout inductor 72 located on the side of the first ignition bracket 5221 close to the second air outlet 5224.

[0062] Furthermore, a plurality of second gas outlets 5211 are provided on the second gas burner mechanism 521 along its axial direction. The second burner assembly 52 further includes a second heat reflecting plate 63 connected to the second gas burner mechanism 521 and located above the second gas outlets 5211.

[0063] Furthermore, the heat transfer ports 41 directly communicate the bottom of the baking chamber 4 with the second burner assembly 52, and the flame and heat can be directly transferred into the baking chamber 4 through the heat transfer ports, effectively reducing the heat loss and the heat transfer path, which is beneficial to improving the thermal efficiency.

[0064] As Figures 1 to 7 shown, the flameout inductor 7 is a thermocouple;

[0065] Further, the flameout inductor 7 is a thermocouple. The working mode of the thermocouple is to directly contact the monitored flame, so it can more directly sense the temperature change of the flame. This setting enables the thermocouple to provide more accurate flame state information, thus ensuring the accuracy of flameout protection. Secondly, the material of the thermocouple is usually selected from high-temperature and corrosion-resistant metals such as platinum and rhodium. These metals have good physical and chemical properties and can resist the high temperature and corrosive environment during the gas combustion process, thus effectively extending the service life of the thermocouple.

[0066] such as Figures 1 to 7 As shown, an installation frame 8 is provided on the oven body 1 above the baking chamber 4, and the timing control component 2 and the gas valve component 3 are both arranged on the installation frame 8.

[0067] Further, the timing control component 2 and the gas valve component 3 are both arranged on the installation frame 8, and the installation frame 8 is located above the baking chamber 4, so that the timing control component 2 and the gas valve component 3 are away from the high-temperature area generated during the baking process, reducing the risk of damage caused by high temperature and being beneficial to improving the safety of the equipment.

[0068] Further, the setting of the installation frame 8 makes the inspection and replacement of the timing control component 2 and the gas valve component 3 more convenient, which is beneficial to reducing the maintenance cost.

[0069] The implementation mode of this embodiment is as follows:

[0070] A gas oven with timing control includes an oven body 1, on which a timing control component 2, a gas valve component 3 electrically connected to the timing control component 2, and a baking cavity 4 are provided. On the baking cavity 4, a burner assembly 5 connected to the gas valve component 3 is provided. On one side of the burner assembly 5, a flameout inductor 7 electrically connected to the timing control component 2 is provided. The flameout inductor 7 is a thermocouple. When a user uses the oven body 1, the baking time of the oven body 1 can be preset through the timing control component 2. The timing control component 2 is electrically connected to the gas valve component 3, and the gas valve component 3 opens the gas pipeline so that the burner assembly 5 can obtain stable gas combustion. When the burner assembly 5 accidentally goes out, the flameout inductor 7 can sense the flameout state of the burner assembly 5, and the flameout inductor 7 can send an electrical signal to the timing control component 2. After receiving the induction signal, the timing control component 2 transmits an instruction to the gas valve component 3 so that the gas valve component 3 closes the gas pipeline, effectively preventing the continuous leakage of gas. This effectively solves the problem that the existing timed gas oven uses a timer to control the opening and closing of the gas valve. When the gas valve remains open, if the burner mechanism accidentally goes out, it will cause continuous leakage of gas, thus posing a safety hazard and endangering personal and property safety. On the oven body 1, a power terminal component 11 connected to the timing control component 2 is provided. The timing control component 2 is connected to the power terminal component 11. When the external power supply is cut off, the timing control component 2 stops working, so that the flameout inductor 7 cannot transmit a signal to the gas valve component 3 through the timing control component 2. The gas valve component 3 cannot receive the signal and then closes the gas valve, stopping the gas supply, effectively avoiding the continuous leakage of gas caused by a power interruption, thereby reducing the risk of fire and explosion. On the oven body 1, a thermostat 12 for detecting the internal temperature of the baking cavity 4 and electrically connected to the timing control component 2 is provided. The thermostat 12 is a snap-action thermostat. The thermostat 12 can detect the internal temperature of the baking cavity 4. The thermostat 12 is electrically connected to the timing control component 2. When the thermostat 12 senses that the internal temperature of the baking cavity 4 is too high, the thermostat 12 disconnects from the timing control component 2 so that the timing control component 2 stops working, and the flameout inductor 7 cannot transmit a signal to the gas valve component 3 through the timing control component 2. The gas valve component 3 cannot receive the signal and then closes the gas valve, stopping the gas supply, effectively preventing fires or equipment damage caused by too high an internal temperature in the baking cavity 4 and greatly enhancing the safety of use.

[0071] The above only uses embodiments to further illustrate the technical content of the present invention to make it easier for readers to understand, but does not mean that the implementation modes of the present invention are limited to this. Any technical extension or re-creation made according to the present invention is protected by the present invention. The protection scope of the present invention is subject to the claims.
