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] Household gas stoves, as one of the kitchen appliances, are a standard feature in every household and have been around for decades. In daily use, gas enters the nozzle through the gas inlet pipe, 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, in order to solve the above problems, it is necessary to provide gas stoves and cooking equipment.

[0006] This disclosure provides a gas stove, which includes a stove body, at least one burner, an air supply assembly, and a control component. The stove body includes a panel and a shell that surrounds the panel to form a bottom space. The panel has a clearance hole and a mounting hole, both of which communicate with the bottom space. At least one burner is mounted in the mounting hole. The burner includes a nozzle assembly and a regulating valve for adjusting the nozzle assembly. Each nozzle assembly includes a nozzle seat and a nozzle disposed on the nozzle seat. The nozzle seat has a gas passage and an air passage, and the nozzle communicates with the gas passage. The air supply assembly includes a fan and an air duct communicating with the fan. The fan is connected to the clearance hole, and the air duct communicates with the air passage. The control component is installed on the regulating valve and is communicatively connected to the fan for adjusting the fan speed.

[0007] The gas stove provided in this embodiment introduces air into the air passage through an adjustment hole, supplying air to the burner. Gas is then sprayed out through the nozzle via the gas passage, where it mixes with the air to ignite the burner. During combustion, the nozzle diameter decreases as the temperature rises, resulting in a lower heat load. However, the lower air temperature around the clearance hole allows for timely cooling of the nozzle after it passes through the air passage, ensuring the nozzle diameter remains constant over long-term use and stabilizing the heat load. This reduces the risk of incomplete combustion leading to a long or even yellow flame. Furthermore, the control unit can recognize the adjustment of the nozzle assembly by the regulating valve and adjust the fan speed according to the combustion conditions. When the regulating valve increases the gas supply, the control unit, communicatively connected to the fan, increases the fan speed, thereby increasing the amount of cold air entering the burner. This increased cold air further enhances the cooling effect on the nozzle. When the regulating valve decreases the gas supply, the control unit reduces the fan speed, reducing noise, extending the fan's lifespan, lowering the risk of backfire, and minimizing the impact on the burner's thermal efficiency.

[0008] In some embodiments, the controller is an encoder that can identify the opening degree of the regulating valve.

[0009] With this configuration, the encoder can identify the opening degree of the regulating valve to determine the amount of gas entering the burner, and then feed back the gas quantity to the fan to adjust the fan speed. The encoder configuration improves the accuracy and sensitivity of the feedback, and increases the stability of the burner operation.

[0010] In some embodiments, the gas passage is vertically arranged, and the nozzle is inclined relative to the gas passage; the outlet of the air passage is parallel to the nozzle and located below the nozzle.

[0011] The inclined nozzle design facilitates the ejection of gas, and the close proximity of the air passage outlet to 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.

[0012] In some embodiments, the burner further includes a base and an ejector tube connected to the base. The base is mounted in a mounting hole, and the nozzle and ejector tube are located at the upper end of the base, communicating with the outside.

[0013] The nozzle and ejector tube are located at the upper end of the base and connected to the outside, which facilitates the direct mixing of the gas with the outside air before entering the ejector tube for combustion. This enhances the cooling effect of the cold air in the air passage on the nozzle, and the additional air passage can further enhance the ejection capacity of the ejector tube.

[0014] In some embodiments, the diameter of the air passage is smaller than the diameter of the gas passage, and the central axis of the ejector tube coincides with the central axis of the nozzle.

[0015] This configuration, with the ejector tube's diameter larger than the gas passage's diameter and their central axes coinciding, improves the accuracy of gas entering the ejector tube from the nozzle and reduces gas leakage. The ejector tube also includes the air passage's outlet, facilitating gas-air mixing, enhancing the ejector tube's ejection capacity, and ensuring thermal stability of combustion.

[0016] In some embodiments, the gas stove also includes a knob, with the regulating valve passing through the clearance hole and the knob positioned above the clearance hole, the knob driving the regulating valve to rotate.

[0017] This design allows users to easily adjust the burner's combustion status using the knob. Rotating the knob opens and closes the regulating valve to control the amount of gas entering the gas passage. The knob's installation in the clearance hole is simple in structure and facilitates the entry of cold air, ensuring that the temperature of the cold air entering the regulating hole is not affected by the burner.

[0018] In some embodiments, the air supply assembly is located in the bottom space, and the air duct includes an air supply pipe and an air distribution seat connected in sequence. The air supply pipe is connected to a fan, and the air distribution seat is connected to multiple air channels.

[0019] This design, with its lower bottom temperature, helps reduce the impact of combustion on the air duct temperature. The gas distributor delivers cold air to each air channel, while simultaneously cooling multiple nozzles, ensuring the stability of the overall heat load of the burner and reducing the occurrence of long flames or even yellow flames due to incomplete combustion.

[0020] In some embodiments, the main body of the stove also includes a cover, which is located below the panel and encloses a portion of the panel to form an air storage space, and the fan is located in the air storage space.

[0021] With this configuration, the cold air drawn in by the fan through the clearance hole can be partially stored inside the air storage space, ensuring the continuity of the amount of air entering the multiple air channels and avoiding the problem of insufficient air supply due to changes in fan speed.

[0022] In some embodiments, the fan is a centrifugal fan.

[0023] Centrifugal fans have a simple structure and are easy to install. They can operate stably for a long time and provide relatively large air volume and pressure with low energy consumption, making it convenient to supply air to multiple air channels.

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

[0025] The gas stove in the cooking equipment disclosed herein uses a fan to introduce air into the air passage through a clearance hole during cooking. This air supply enhances the ejector tube's ejection capability and cools the nozzle during combustion, keeping the nozzle diameter constant and thus stabilizing the heat load. This reduces the occurrence of long flames or even yellow flames due to incomplete combustion, improving the performance of the cooking equipment. The control unit can recognize the adjustment of the regulating valve on the nozzle assembly and can change the fan speed according to the combustion situation. When the regulating valve increases the gas supply, the control unit, communicatively connected to the fan, increases the fan speed, thereby increasing the amount of cold air entering. This increased cold air further enhances the cooling effect on the 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 Figures 2 to 5 This disclosure provides a gas stove 10, which includes a stove body 1, at least one burner 2, an air supply assembly 3, and a control component 4. 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 a clearance hole 111 and a mounting hole 112, both of which are connected to the bottom space 13.

[0041] At least one burner 2 is mounted in the mounting hole 112. The burner 2 includes a nozzle assembly 22 and a regulating valve 24 for adjusting the nozzle assembly 22. Exemplarily, the nozzle assembly 22 is located in the mounting hole 112. The regulating valve 24 is capable of adjusting the amount of gas entering the burner. Each nozzle assembly 22 includes a nozzle seat 221 and a nozzle 222 disposed in the nozzle seat 221. The nozzle seat 221 has a gas passage 2211 and an air passage 2212, and the nozzle 222 communicates with the gas passage 2211.

[0042] The air supply assembly 3 includes a fan 31 and an air duct 32 communicating with the fan 31. The fan 31 is connected to a clearance hole 111, and the air duct 32 is connected to an air passage 2212. Exemplarily, the fan 31 is used to obtain air from the outside and deliver it into the air passage 2212 through the air duct 32. A control element 4 is mounted on a regulating valve 24 and is communicatively connected to the fan 31 for adjusting the rotational speed of the fan 31.

[0043] The gas stove 10 provided in this embodiment introduces air into the air passage 2212 through the fan 31 via the regulating hole, providing air to the burner 2. Gas passes through the gas passage 2211 and is ejected through the nozzle 222. At this time, the gas mixes with the air, causing the burner 2 to burn. During the combustion process, the diameter of the nozzle 222 will decrease due to the increase in temperature, and the heat load will become lower and lower. However, because the air temperature around the clearance hole 111 is low, it can cool the nozzle 222 in time after being ejected through the air passage 2212, so that the diameter of the nozzle 222 remains unchanged under long-term use, thereby stabilizing the heat load and reducing the phenomenon of long flames or even yellow flames due to incomplete combustion.

[0044] Furthermore, the control unit 4 can recognize the adjustment of the regulating valve 24 to the nozzle assembly 22 and can change the speed of the fan 31 according to the combustion situation. When the regulating valve 24 controls the increase of gas, the control unit 4 is communicatively connected to the fan 31 to increase the speed of the fan 31, thereby increasing the amount of cold air entering. The increase in cold air can further enhance the cooling effect on the nozzle 222. When the regulating valve 24 controls the decrease of gas, the control unit 4 controls the fan 31 to reduce the speed, which can reduce noise, extend the service life of the fan 31, reduce the risk of backfire and the impact on the thermal efficiency of the burner 2.

[0045] For example, the upper part of the burner 2 protrudes from the panel 11, and the lower part of the burner 2 is located in the bottom space 13. There is a certain distance between the clearance hole 111 and the mounting hole 112, which reduces the impact of the burner 2 on the air near the clearance hole 111 when it is burning, so that the air near the clearance hole 111 is kept at a low temperature.

[0046] For example, the opening of the regulating valve 24 is used to control the amount of gas entering the gas passage 2211. The blower 31 draws in cold air through the clearance hole 111. After the control unit 4 detects the opening of the regulating valve 24, it controls the speed of the blower 31 to increase or decrease, so that the amount of cold air entering the air passage 2212 is automatically adjusted according to the amount of gas.

[0047] In some embodiments, the control element 4 is an encoder capable of identifying the opening degree of the regulating valve 24. This configuration allows the encoder to identify the opening degree of the regulating valve 24 to determine the amount of gas entering the burner 2, and then feeds back the gas quantity to the fan 31 to adjust its speed. The encoder improves the accuracy and sensitivity of the feedback, increasing the stability of the burner 2. It is understood that the encoder-fan 31 control relationship is a conventional setup. This embodiment utilizes the opening degree of the regulating valve 24 to match the speed of the fan 31.

[0048] For example, when the knob 5 is rotated to adjust the fire level, the encoder can read the fire level in real time, control the speed of the centrifugal fan 31 through the change of voltage, and adjust the amount of air introduced.

[0049] refer to Figure 3 For example, the encoder is mounted around the control valve 24. In other embodiments, the encoder may also be located at a position on the control valve 24 that identifies the degree of opening or closing of the control valve 24.

[0050] For example, when the encoder detects that the opening of the regulating valve 24 is small, the gas flow rate in the burner 2 is low and the temperature is not high. The encoder controls the fan 31 to maintain a low speed, resulting in low noise and extended service life. When the opening of the regulating valve 24 increases, leading to a higher gas flow rate and temperature in the burner 2, the encoder controls the fan 31 to increase its speed based on the valve opening. This increases the amount of cool air entering the air passage 2212, providing more air to cool the nozzle 222 and ensuring complete combustion.

[0051] For example, when the opening of the regulating valve 24 changes from large to small, the encoder recognizes that the opening of the regulating valve 24 has decreased, the amount of gas decreases, and therefore the speed of the control fan 31 decreases, so that the amount of cold air entering decreases, ensuring the stability of combustion, reducing the risk of backfire, and ensuring the thermal efficiency of the burner 2.

[0052] In other embodiments, the control element 4 may also control the rotational speed of the fan 31 in other ways.

[0053] refer to Figure 2 In some embodiments, the gas passage 2211 is vertically arranged, and the nozzle 222 is inclined relative to the gas passage 2211; 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 ejection of gas, 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.

[0054] In other embodiments, the nozzle 222 may also be horizontally positioned. The outlet of the air passage 2212 is located above or around the nozzle 222.

[0055] refer to Figure 2In some embodiments, the burner 2 further includes a base 21 and an ejector tube 23 connected to the base 21. The base 21 is mounted in the mounting hole 112. The nozzle 222 and the ejector tube 23 are located at the upper end of the base 21 and are connected to the outside. The location of the nozzle 222 and the ejector tube 23 at the upper end of the base 21 and their connection to the outside facilitates the direct mixing of the combustion gas with the outside air before entering the ejector tube 23 for combustion. This enhances the cooling effect of the cold air in the air passage 2212 on the nozzle 222, and the additional air provided by the air passage 2212 can further enhance the ejection capacity of the ejector tube 23.

[0056] refer to Figure 1 and Figure 3 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.

[0057] 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.

[0058] For example, the air distribution seat 322 is located below the base 21 and is horizontally arranged. The temperature below the base 21 is lower. The arrangement of the air distribution seat 322 helps to reduce the temperature impact on the air supply channel, making it difficult for the temperature of cold air to rise when it flows through the air distribution seat 322, and also has a cooling effect on the base 21.

[0059] refer to Figure 2 In some embodiments, the diameter of the air passage 2212 is smaller than the diameter of the gas passage 2211, and the central axis of the ejector tube 23 coincides with the central axis of the nozzle 222. This arrangement, with the diameter of the ejector tube 23 larger than the diameter of the gas passage 2211 and their central axes coinciding, improves the accuracy of gas entering the ejector tube 23 from the nozzle 222 and reduces gas leakage. The ejector tube 23 can also include the outlet of the air passage 2212, facilitating gas-air mixing, improving the ejection capacity of the ejector tube 23, and ensuring thermal stability of combustion.

[0060] 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 are located within the diameter of the ejector tube 23.

[0061] refer to Figure 1 and Figure 3 In some embodiments, the gas stove 10 also includes a knob 5, with a regulating valve 24 passing through a clearance hole 111. The knob 5 is located above the clearance hole 111, and the knob 5 drives the regulating valve 24 to rotate. This arrangement allows the user to easily adjust the combustion status of the burner 2. The rotation of the knob 5 causes the regulating valve 24 to open and close, controlling the gas intake in the gas passage 2211. The knob 5's installation in the clearance hole 111 is simple in structure and facilitates the entry of cold air, ensuring that the temperature of the cold air entering the regulating hole is not affected by the burner 2.

[0062] For example, there is a gap between the knob 5 and the panel 11, and the regulating valve 24 is located at a part of the clearance hole 111. After the fan 31 is started, cold air can enter the air storage space 15 through the gap and the clearance hole 111.

[0063] refer to Figures 2 to 4 In some embodiments, the air supply assembly 3 is located in the bottom space 13, and the air duct 32 includes an air supply pipe 321 and an air distribution seat 322 connected in sequence. The air supply pipe 321 is connected to the fan 31, and the air distribution seat 322 is connected to multiple air channels 2212. This arrangement results in a lower temperature in the bottom space 13, which helps to reduce the temperature impact on the air duct 32 during combustion. The air distribution seat 322 delivers cold air to each air channel 2212, while simultaneously cooling multiple nozzles 222, ensuring the stability of the overall heat load of the burner 2 and reducing the occurrence of long flames or even yellow flames due to incomplete combustion.

[0064] For example, the vertical projection of the air distribution seat 322 is triangular, with each of the three corners of the triangle having a conduit connected to the air passage 2212. In other embodiments, the air distribution seat 322 can connect to one, two, or more air passages 2212. The shape of the air distribution seat 322 can also be cylindrical, square, or irregular.

[0065] refer to Figure 3 In some embodiments, the cooktop body 1 further includes a cover 14, which is located below the panel 11 and encloses a portion of the panel 11 to form a storage space 15. The fan 31 is located in the storage space 15. This arrangement allows the cold air drawn in by the fan 31 through the clearance hole 111 to be partially stored inside the storage space 15, ensuring the continuity of airflow into the multiple air channels 2212 and preventing insufficient air supply due to changes in the fan 31's rotation speed.

[0066] For example, the area surrounded by the housing 14 includes a clearance hole 111 such that the clearance hole 111 communicates with the air storage space 15. The housing 14 is provided with a through hole that communicates with a plurality of air supply pipes 321.

[0067] For example, both clearance holes 111 are connected to the air storage space 15. The fan 31 is located between the two clearance holes 111 in the air storage space 15 and is connected to two air supply pipes 321. One air supply pipe 321 is connected to the air inlet of a distribution seat 322. The distribution seat 322 is connected to three air channels 2212 respectively. The air entering the distribution seat 322 is cooled by the three air channels 2212 and provides air to the corresponding three nozzles 222 at the same time.

[0068] In some embodiments, the fan 31 is a centrifugal fan 31. The centrifugal fan 31 has a simple structure, is easy to install, can operate stably for a long time, and can provide a relatively large air volume and pressure with low energy consumption, making it convenient to supply air to multiple air channels 2212.

[0069] In other embodiments, the fan 31 may also be an axial flow fan 31 or other types of fans 31.

[0070] 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, the gas stove 10 introduces air into the air passage 2212 through the clearance hole 111, providing air to the injector tube 23 of the burner 2 to enhance the injection capability of the injector tube 23. During combustion, the blower 31 cools the nozzle 222, keeping the diameter of the nozzle 222 constant, thereby stabilizing the heat load and reducing the phenomenon of long flames or even yellow flames due to incomplete combustion, thus increasing the performance of the cooking device 100. The control unit 4 can recognize the adjustment of the regulating valve 24 to the nozzle assembly 22 and can change the speed of the blower 31 according to the combustion situation. When the regulating valve 24 controls the increase of gas, the control unit 4, communicatively connected to the blower 31, increases the speed of the blower 31, thereby increasing the amount of cold air entering. The increased cold air further enhances the cooling effect on the nozzle 222, extending the service life of the gas stove 10 and the cooking device 100.

[0071] 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.

[0072] 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.

[0073] 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.
