Description

Technical Field

[0001] This disclosure relates to the field of household kitchen appliances, and in particular to gas stoves and cooking equipment. Background Technology

[0002] As a kitchen appliance, the gas stove is a standard feature in every household and has been around for decades. In daily use, gas enters the nozzle through the air intake channel, diffuses, and enters the burner injector tube. At the same time, a negative pressure is created, drawing in surrounding air to mix the gas and air. The natural mixing of gas and air forms a combustible gas, which is then burned.

[0003] For enhanced safety, existing gas stoves utilize top-intake burners. A cooling fan is integrated into the stove's chassis to dissipate heat from the interior.

[0004] However, the ejector tubes of current top-intake burners are relatively short due to structural volume limitations, and their air ejection capacity is weaker compared to bottom-intake burners, making it difficult to increase the heat load. At the same time, as the burner is used for a long time, the nozzle orifice diameter will become smaller at high temperatures, resulting in a lower heat load and incomplete combustion, leading to a long flame or even a yellow flame. Utility Model Content

[0005] Therefore, it is necessary to provide gas stoves and cooking equipment to address the above issues.

[0006] This disclosure provides a gas stove, which includes a stove body and a burner. The stove body includes a panel and a shell that surrounds the panel to form a bottom space. The panel has adjustment holes and mounting holes, both of which are connected to the bottom space. The burner is installed on the stove body and includes at least two bases, multiple nozzle assemblies, and multiple ejector tubes. The bases are installed in the mounting holes. Each nozzle assembly includes a nozzle seat with a gas passage and an air passage, and a nozzle connected to the gas passage. The nozzle assemblies are correspondingly arranged with the ejector tubes, and the ejector tubes are connected to the nozzles and the air passages. The burner also includes a gas supply assembly and an adjusting component. The inlet of the gas supply assembly is connected to the outside through the adjustment hole, and the outlet of the gas supply assembly is connected to the inlet of the air passage. The adjusting component is at least partially movably located within the gas supply passage of the gas supply assembly to change the flow area of ​​the gas supply passage.

[0007] The gas stove provided in this embodiment allows air to enter the air passage sequentially through an adjustment hole and a gas supply assembly, providing air to the injector tube of the burner to enhance its injection capability. Gas flows through the gas passage and enters the injector tube through the nozzle, enabling combustion. During combustion, the nozzle diameter decreases due to rising temperature, resulting in a lower heat load. Because the temperature around the adjustment hole is low, the cold air entering through the adjustment hole and exiting parallel to the nozzle can effectively cool the nozzle, maintaining its diameter and stabilizing the heat load. This reduces the risk of incomplete combustion leading to a long or even yellow flame. Furthermore, as the burner base temperature rises with prolonged use, the adjustable element, movably inserted into the gas supply assembly, can alter the flow area of ​​the gas supply assembly, increasing the amount of cold air entering. This increased cold air volume enhances the cooling effect on the base and nozzle, extending the burner's lifespan.

[0008] In some embodiments, the adjusting member includes a fixed section, a telescopic section, and a blocking end connected in sequence. The fixed section is fixed to the base, the blocking end is located in the air supply channel of the air supply assembly, and the telescopic section can deform to drive the blocking end to move in the air supply channel of the air supply assembly.

[0009] This design allows the telescopic section to move within the air supply channel of the air supply component, thereby changing the flow area of ​​the air supply channel. This facilitates control over the intake volume of cold air entering the air channel, further enhancing the air replenishment capability to strengthen the ejector tube's ejection capability. At the same time, it facilitates the cooling of the nozzle, keeping the nozzle diameter constant and thus stabilizing the heat load.

[0010] In some embodiments, the material of the telescopic section is a thermally expanding material.

[0011] Thermally expandable materials can change in volume or length according to temperature changes. With this design, the expansion section extends when the temperature rises, causing the sealing end to extend out of the air supply component, increasing the air circulation area in the air supply channel. When the temperature drops, the expansion section returns to its original shape, so that the sealing end is completely located in the air supply channel of the air supply component, reducing the air circulation area.

[0012] In some embodiments, the air supply assembly is located in the bottom space. The air supply assembly includes an air inlet channel, a fan, an air delivery pipe, and an air distribution seat connected in sequence. The air inlet channel is connected to an adjustment hole. The fan is used to supply air to the air channel. The air delivery pipe is connected to the air distribution seat, and an adjustment element is provided in the air supply channel of the air distribution seat. The air distribution seat is connected to multiple air channels.

[0013] With this configuration, the fan draws in cold air through the regulating hole and then sequentially passes through the air inlet channel, the air supply pipe, and the air distribution seat's air supply channel into the air channel. The regulating component controls the air intake volume within the air distribution seat's air supply channel, and the air distribution seat delivers the cold air to each air channel, achieving cooling of multiple nozzles. This ensures the stability of the burner's overall thermal load and reduces the occurrence of long flames or even yellow flames due to incomplete combustion.

[0014] In some embodiments, the diameter of the telescopic section is smaller than the diameter of the fixed section, and the cross-sectional area of ​​the sealing end is smaller than the cross-sectional area of ​​the air supply channel of the gas distributor.

[0015] With this configuration, the fixed section is used to transfer heat, while the diameter of the telescopic section is smaller than that of the fixed section, increasing the thermal sensitivity of the telescopic section. This facilitates sensing temperature changes and allowing it to quickly extend or shorten to adjust the intake of cold air. The cross-sectional area of ​​the sealing end is smaller than that of the air supply channel of the gas distributor, allowing air to continuously enter the air channel to supply air to the burner's ejector tube, thereby enhancing the ejector tube's ejection capability.

[0016] In some embodiments, the gas distributor is located below the base and is horizontally positioned, and the adjusting member extends and retracts in the vertical direction.

[0017] The temperature below the base is lower. The setting of the air distribution seat helps to reduce the temperature impact on the air supply channel, so that the temperature of cold air does not rise easily when it flows through the air distribution seat. It also has a cooling effect on the base. The vertically set adjustment component facilitates the transfer of heat from top to bottom, so that the expansion section can deform according to temperature changes.

[0018] In some embodiments, the gas stove also includes a knob and an adjustment valve connected to the knob. The adjustment valve is installed in an adjustment hole, and the knob drives the adjustment valve to rotate for adjusting the nozzle assembly.

[0019] With this configuration, turning the knob can open and close the regulating valve to control the amount of gas entering the gas passage. The regulating hole is located at a certain distance from the burner, so that the temperature of the cold air entering the regulating hole is not affected by the burner.

[0020] In some embodiments, the air supply assembly also includes an encoder mounted on the regulating valve and communicatively connected to the fan to control the fan speed.

[0021] With this setup, the encoder can identify the opening of the regulating valve to determine the amount of gas entering the burner, and then feed back the gas amount to the fan to adjust the fan speed, which helps to control and regulate the amount of air introduced into the gas distributor.

[0022] In some embodiments, the gas passage is vertically arranged, the nozzle is inclined relative to the gas passage, and the outlet of the air passage is parallel to the nozzle and located below the nozzle.

[0023] The inclined nozzle setting facilitates the injection of gas into the injector tube. The close distance between the air passage outlet and the nozzle promotes contact between cold air and the nozzle, thereby directly cooling the nozzle and ensuring thorough mixing of air and gas, reducing the occurrence of long flames or even yellow flames due to incomplete combustion.

[0024] This disclosure provides a cooking device, which includes the gas stove described above.

[0025] The gas stove in the cooking equipment disclosed herein allows air to enter the air passage sequentially through the regulating hole and the gas supply component during cooking. This provides air to the burner's injector tube, enhancing its ejection capability. Furthermore, it cools the nozzle during combustion, maintaining a constant nozzle diameter to stabilize the heat load and reduce the occurrence of long or even yellow flames due to incomplete combustion, thus improving the performance of the cooking equipment. The regulating component, movably inserted into the gas supply component, alters the flow area of ​​the gas supply component, increasing the amount of cold air entering. This increased cold air volume enhances the cooling effect on the base and nozzle, extending the service life of the gas stove and cooking equipment. Attached Figure Description

[0039] refer to Figure 1 , Figure 1 The overall structure of the gas stove 10 according to an embodiment of this disclosure is shown. This disclosure relates to the field of household kitchen appliance technology. The gas stove 10 can be used alone or combined with a range hood and cooking appliances to form an integrated stove as a combined kitchen appliance.

[0040] Combination Figure 2 This disclosure provides a gas stove 10, which includes a stove body 1 and a burner 2. The stove body 1 includes a panel 11 and a shell 12 that surrounds the panel 11 to form a bottom space 13. The panel 11 has an adjustment hole 111 and a mounting hole 112, both of which are connected to the bottom space 13.

[0041] The burner 2 is mounted on the cooktop body 1. The burner 2 includes at least two bases 21, multiple nozzle assemblies 22, and multiple ejector tubes 23. Exemplarily, each base 21 includes multiple nozzle assemblies 22 and an equal number of ejector tubes 23. The base 21 is mounted in mounting holes 112. Each nozzle assembly 22 includes a nozzle seat 221 with a gas passage 2211 and an air passage 2212, and a nozzle 222 communicating with the gas passage 2211. The nozzle assembly 22 is correspondingly disposed with the ejector tube 23, and the ejector tube 23 communicates with the nozzle 222 and the air passage 2212. Exemplarily, one nozzle 222 and one air passage 2212 are correspondingly disposed with one ejector tube 23.

[0042] The burner 2 also includes an air supply assembly 24 and an adjusting member 25. The inlet of the air supply assembly 24 is connected to the outside through an adjusting hole 111, and the outlet of the air supply assembly 24 is connected to the inlet of the air passage 2212. Exemplarily, air passes sequentially through the adjusting hole 111, the air supply assembly 24, and the air passage 2212, and finally enters the ejector tube 23. The adjusting member 25 is at least partially movable within the air supply passage of the air supply assembly 24, and is used to change the flow area of ​​the air supply passage.

[0043] The gas stove 10 provided in this embodiment has a main body 1 for mounting a burner 2. Air enters the air passage 2212 sequentially through the regulating hole 111 and the gas supply component 24, providing air to the injector tube 23 of the burner 2. Gas enters the injector tube 23 through the gas passage 2211 and the nozzle 222. After the air and gas mix, the burner 2 can burn, which enhances the injection capacity of the injector tube 23. The increased air further improves the air supply capacity of the burner 2. At the same time, the temperature rise during combustion causes the diameter of the nozzle 222 to decrease, resulting in a lower heat load. Because the temperature around the regulating hole 111 is low, the cold air entering from the regulating hole 111 is ejected parallel to the nozzle 222, which can cool the nozzle 222 in time, keeping the diameter of the nozzle 222 constant and thus stabilizing the heat load. This reduces the phenomenon of long flames or even yellow flames due to incomplete combustion.

[0044] On the other hand, as the combustion time of burner 2 increases, the overall temperature will rise. The regulating member 25 can be movably inserted into the gas supply assembly 24 to increase the flow area of ​​the gas supply assembly 24, thereby increasing the amount of cold air entering the gas supply assembly 24. The increase in cold air can enhance the cooling effect on the base 21 and nozzle 222, and extend the service life of burner 2.

[0045] For example, the panel 11 has two symmetrical mounting holes 112, and the burner 2 has two bases 21, each base 21 being mounted in one mounting hole 112 such that the nozzle assembly 22 and the ejector tube 23 are both located on the panel 11. In other embodiments, there may be only one mounting hole 112 and one base 21, or multiple mounting holes 112 and multiple bases 21, with the number of mounting holes 112 being the same as the number of bases 21.

[0046] For example, each base 21 includes three nozzle assemblies 22, and each nozzle assembly 22 is provided with a corresponding ejector tube 23. In other embodiments, each base 21 may include two nozzle assemblies 22 or other numbers of nozzle assemblies 22, the number of nozzle assemblies 22 being the same as the number of ejector tubes 23.

[0047] For example, the gas supply assembly 24 and the regulating member 25 are both located in the bottom space 13.

[0048] refer to Figure 2 and Figure 4 In some embodiments, the adjusting member 25 includes a fixed section 251, a telescopic section 252, and a sealing end 253 connected in sequence. The fixed section 251 is fixed to the base 21, and the sealing end 253 is located within the air supply channel of the air supply assembly 24. The telescopic section 252 can deform to move the sealing end 253 within the air supply channel of the air supply assembly 24. This configuration allows the telescopic section 252 to move the sealing end 253 within the air supply channel of the air supply assembly 24, thereby changing the flow area of ​​the air supply channel. This facilitates control of the intake volume of cold air into the air channel 2212, further enhancing the air replenishment capability to strengthen the ejector tube 23's ejection capability. Simultaneously, it facilitates cooling of the nozzle 222, ensuring that the nozzle 222's diameter remains constant, thus stabilizing the heat load.

[0049] For example, both the fixed section 251 and the telescopic section 252 are cylindrical in shape. The sealing end 253 has a certain cross-sectional area along the airflow direction. When the sealing end 253 moves under the action of the telescopic section 252, it can change the airflow surface within the air supply channel of the air supply assembly 24. For example, the sealing end 253 is a cube, or the sealing end 253 has a certain thickness perpendicular to the airflow direction. In other embodiments, the fixed section 251 can be an irregular shape or other shapes. The shape of the telescopic section 252 is conducive to deformation. The shape of the sealing end 253 can also be triangular, square, circular, or other irregular shapes.

[0050] In some embodiments, the telescopic section 252 is made of a thermally expandable material. Thermally expandable materials can change in volume or length according to temperature variations. This configuration allows the telescopic section 252 to extend when the temperature rises, causing the sealing end 253 to protrude from the air supply assembly 24, increasing the airflow area within the air supply channel. When the temperature decreases, the telescopic section 252 returns to its original shape, ensuring the sealing end 253 is completely within the air supply channel of the air supply assembly 24, thus reducing the airflow area.

[0051] For example, the telescopic section 252 is capable of deformation along the extension direction. When the burner 2 is not burning, the telescopic section 252 is in its initial state. When the burner 2 is burning, the temperature of the base 21 rises, and heat can be transferred to the telescopic section 252 through the fixed section 251. The thermal expansion material causes the telescopic section 252 to elongate along the extension direction according to the temperature change. In other embodiments, the telescopic section 252 can expand diametrically to cause the sealing end 253 to change the flow area of ​​the gas supply channel within the gas supply assembly 24.

[0052] For example, the telescopic section 252 is made of metal to facilitate heat transfer and deformation.

[0053] refer to Figure 2 , Figure 4 and Figure 5 In some embodiments, the air supply assembly 24 is located in the bottom space 13. The air supply assembly 24 includes an air inlet channel 241, a fan 242, an air delivery pipe 243, and an air distribution seat 244 connected in sequence. The air inlet channel 241 is connected to the adjustment hole 111. The fan 242 is used to supply air to the air channel 2212. The air delivery pipe 243 is connected to the air distribution seat 244, and an adjustment member 25 is provided in the air supply channel of the air distribution seat 244. The air distribution seat 244 is connected to multiple air channels 2212. With this configuration, after the fan 242 draws in cold air through the regulating hole 111, it enters the air passage 2212 sequentially through the air inlet passage 241, the air supply pipe 243, and the air distribution seat 244. The regulating component 25 controls the air intake volume in the air supply passage of the air distribution seat 244. The air distribution seat 244 delivers cold air to each air passage 2212, thereby cooling multiple nozzles 222, ensuring the stability of the overall heat load of the burner 2, and reducing the phenomenon of long flames or even yellow flames due to incomplete combustion.

[0054] For example, the fan 242 is located in the air inlet channel 241 between two adjustment holes 111 in the bottom space 13. The air inlet channel 241 is formed by the surrounding cover and panel 11 of the fan 242. The adjustment holes 111 are connected to the air inlet channel 241. The cover is provided with through holes that are connected to a plurality of air supply pipes 243.

[0055] For example, there are two regulating holes 111 that are both connected to the air inlet channel 241. The fan 242 is located in the air inlet channel 241 and is connected to two air supply pipes 243. One air supply pipe 243 is connected to the air inlet of a distribution seat 244. The distribution seat 244 is provided with a movable adjusting member 25. The amount of air entering the distribution seat 244 is controlled by the movement of the adjusting member 25. The remaining part of the distribution seat 244 is connected to three air channels 2212 respectively. The air entering the distribution seat 244 is cooled by the three air channels 2212 and provides air to the corresponding three nozzles 222 and the corresponding ejector tubes 23.

[0056] refer to Figure 2 In some embodiments, the diameter of the telescopic section 252 is smaller than the diameter of the fixed section 251, and the cross-sectional area of ​​the sealing end 253 is smaller than the cross-sectional area of ​​the air supply channel of the air distributor 244. This arrangement allows the fixed section 251 to transfer heat, and the smaller diameter of the telescopic section 252 increases its thermal sensitivity, facilitating the sensing of temperature changes and allowing it to quickly extend or shorten to adjust the intake of cold air. The smaller cross-sectional area of ​​the sealing end 253 compared to the air supply channel of the air distributor 244 allows air to continuously enter the air channel 2212 to supply air to the injector 23 of the burner 2, enhancing the ejection capability of the injector 23.

[0057] refer to Figure 2 and Figure 4 In some embodiments, the air distribution seat 244 is located below the base 21 and is horizontally arranged, while the adjusting member 25 extends and retracts vertically. The temperature below the base 21 is lower, and the arrangement of the air distribution seat 244 helps to reduce the temperature impact on the air supply channel, making it less likely for the temperature of cold air to rise when it flows through the air distribution seat 244. It also has a cooling effect on the base 21. The vertically arranged adjusting member 25 facilitates the transfer of heat from top to bottom, thereby making it easier for the extension section 252 to deform according to temperature changes.

[0058] For example, the air distribution seat 244 is arranged parallel to the bottom of the base 21 and at a certain distance from the bottom of the base 21. The adjusting member 25 consists of a fixed section 251, a telescopic section 252, and a sealing end 253 from top to bottom. When the telescopic section 252 is in its initial non-telescopic state, the bottom of the sealing end 253 is flush with the bottom of the air distribution seat 244, and the top of the sealing end 253 is located inside the air distribution seat 244 at a preset distance from the top of the air distribution seat 244. This preset distance is the minimum flow area. When the telescopic section 252 is heated and extends downward, the sealing end 253 moves downward, so that the distance between the top of the sealing end 253 and the top of the air distribution seat 244 gradually exceeds the preset distance. At this time, the flow area increases, and the air intake increases. When the top of the sealing end 253 is flush with the bottom of the air distribution seat 244, the flow area is at its maximum, and the telescopic section 252 no longer deforms. When the temperature drops, the telescopic section 252 gradually shortens upward.

[0059] refer to Figure 1 and Figure 5 In some embodiments, the gas stove 10 also includes a knob 3 and a regulating valve 4 connected to the knob 3. The regulating valve 4 is installed in the regulating hole 111, and the knob 3 drives the regulating valve 4 to rotate to adjust the nozzle assembly 22. With this configuration, the rotation of the knob 3 can drive the regulating valve 4 to open and close, controlling the amount of gas entering the gas passage 2211. The regulating hole 111 is located at a certain distance from the burner 2 at the knob 3, so that the temperature of the cold air entering the regulating hole 111 is not affected by the burner 2.

[0060] For example, there is a gap between the knob 3 and the panel 11, and the regulating valve 4 is located at part of the regulating hole 111. After the fan 242 is started, cold air can enter the air intake channel 241 through the gap and the regulating hole 111.

[0061] refer to Figure 5In some embodiments, the gas supply assembly 24 further includes an encoder 245, which is mounted on the regulating valve 4 and communicatively connected to the fan 242 to control the speed of the fan 242. With this configuration, the encoder 245 can identify the opening degree of the regulating valve 4 to determine the amount of gas entering the burner 2, and feed back the gas quantity to the fan 242 to adjust its speed, thus facilitating the control and regulation of the amount of air introduced into the gas distributor 244. It is understood that the control relationship between the encoder 245 and the fan 242 is a conventional setup. This disclosure embodiment utilizes the opening degree of the regulating valve 4 to match the speed of the fan 242.

[0062] refer to Figure 5 For example, encoder 245 is mounted around the control valve 4. In other embodiments, encoder 245 may also be located at a position on the control valve 4 that allows the valve body to be identified in terms of opening degree.

[0063] For example, when the encoder 245 detects a small valve opening, the flame of the burner 2 is small and the temperature is not high, and the encoder 245 controls the fan 242 to maintain a low speed. When the valve opening increases and the temperature of the burner 2 rises, the encoder 245 controls the fan 242 to increase its speed according to the valve opening, thereby increasing the amount of cold air entering the air passage 2212, providing more air to cool the nozzle 222 while ensuring complete combustion.

[0064] For example, when the valve body opening changes from large to small, the temperature of the base 21 is high due to the previous combustion and is difficult to drop quickly, so the regulating member 25 cannot retract quickly to reduce the amount of air entering. At this time, the encoder 245 recognizes that the valve body opening has decreased and controls the fan 242 to reduce its speed. The two work together to reduce the amount of cold air entering, thus ensuring the stability of combustion.

[0065] refer to Figure 2 In some embodiments, the gas passage 2211 is vertically arranged, the nozzle 222 is inclined relative to the gas passage 2211, and the outlet of the air passage 2212 is parallel to the nozzle 222 and located below the nozzle 222. The inclined arrangement of the nozzle 222 facilitates the injection of gas into the injector tube 23, and the close distance between the outlet of the air passage 2212 and the nozzle 222 facilitates the contact between cold air and the nozzle 222, thereby directly cooling the nozzle 222 and promoting thorough mixing of air and gas, reducing the phenomenon of long flames or even yellow flames due to incomplete combustion.

[0066] For example, the ejector tube 23 is also arranged parallel to the nozzle 222, such that the outlet of both the nozzle 222 and the air passage 2212 is located within the diameter of the ejector tube 23. In other embodiments, the nozzle 222 may also be arranged horizontally, with the outlet of the air passage 2212 located above or around the nozzle 222.

[0067] refer to Figure 6 This disclosure provides a cooking device 100, which includes the aforementioned gas stove 10. In the cooking device 100 provided by this disclosure, when cooking food, air enters the air passage 2212 sequentially through the regulating hole 111 and the gas supply assembly 24, providing air to the injector tube 23 of the burner 2 to enhance the injector tube 23's ejection capacity. During combustion, the nozzle 222 is cooled, ensuring the nozzle 222's diameter remains constant, thereby stabilizing the heat load and reducing the occurrence of long flames or even yellow flames due to incomplete combustion, thus increasing the performance of the cooking device 100. The regulating member 25 can be movably inserted into the gas supply assembly 24, changing the flow area of ​​the gas supply assembly 24 to increase the amount of cold air entering. This increased cold air enhances the cooling effect on the base 21 and the nozzle 222, extending the service life of the gas stove 10 and the cooking device 100.

[0068] For example, the cooking device 100 may be an integrated stove, which is a one-piece design, with a gas stove 10 on the upper part and a steam oven 20 or a steam oven or other steam oven on the lower part.

[0069] The technical features of the above-disclosed embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The embodiments disclosed above merely illustrate several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
