Description

Technical Field

[0001] The utility model relates to the technical field of stoves, in particular to a gas stove. Background Art

[0002] Gas stoves are kitchen appliances that use petroleum gas, artificial gas, natural gas and other gases as fuel for heating. When the gas stove is working, the gas is transported from the air inlet pipe, regulated by the gas proportion valve and enters the burner head, and mixed with a part of the air. The mixed gas is ejected from the gas outlet hole of the fire cover and ignited by the ignition device to form a flame, which is used to heat the cooker placed on the pot support.

[0003] Cooking utensils will produce fumes during the cooking process. After long-term use, the grease condensed from the fumes and the food soup that overflows from the cooking utensils during the cooking process will remain on the gas stove and block the fire holes of the fire cover. The fire holes will not be able to spray out the mixed gas normally, and the fire holes may even be blocked and unable to ignite and burn, which will directly affect the performance of the gas stove.

[0004] However, as users' demands for the heating efficiency of gas stoves continue to increase, the diameter of the gas outlet fire holes on the fire covers of gas stoves gradually becomes smaller, and cleaning of the gas outlet fire holes becomes more and more difficult. Utility Model Content

[0045] A gas stove is a kitchen appliance that uses gas fuels such as artificial gas, natural gas or liquefied petroleum gas to directly heat the cooker. When the gas stove is working, the gas is transported from the air inlet pipe, regulated by the gas valve, and enters the burner head, while mixing with a portion of air. The mixed gas is ejected from the gas outlet hole of the fire cover and ignited by the ignition device to form a flame, which is used to heat the cooker placed on the pot support.

[0046] Cooking utensils will produce oil smoke during cooking. After long-term use, the oil stains condensed from the oil smoke and the food soup overflowing from the cookers during cooking will remain on the gas stove, affecting the appearance and cleanliness of the gas stove. What is more serious is that the oil stains and food residues will block the gas outlet holes of the fire cover, and the gas outlet holes will not be able to spray mixed gas normally, affecting the heating temperature of the cooker, and the taste of the food cannot be guaranteed. Even after the gas outlet holes are blocked, they cannot be ignited and burned, which will directly affect the performance of the gas stove.

[0047] However, as users' demand for gas stove heating efficiency continues to increase, the diameter of the gas outlet holes on the gas stove's fire cover has gradually become smaller, making it increasingly difficult to clean the gas outlet holes. In actual use, it is difficult for users to clean them by conventional cleaning methods such as wiping, and professional maintenance personnel are required to clean them according to the instructions in the product manual.

[0048] To solve the above problems, the present application provides a gas stove 100, such as Figure 1 As shown, Figure 1The present invention provides a schematic diagram of the structure of a gas stove 100. The gas stove 100 includes a bottom shell 11, which encloses a mounting cavity 10 having an opening. The opening is connected to the mounting cavity 10, so that other relevant components of the gas stove 100 can be installed in the mounting cavity 10 of the bottom shell 11. The bottom shell 11 can provide support for the relevant components installed in the mounting cavity 10 thereof, as well as a certain degree of protection, to ensure that the gas stove 100 can work normally.

[0049] On this basis, see Figure 1 The gas stove 100 provided in the present application further includes a burner 2. The burner 2 is a core component of the gas stove 100, and the burner 2 includes a burner head 21, which is disposed in the mounting cavity 10 of the bottom shell 11. A gas mixing cavity is formed inside the burner head 21. The burner head 21 can mix the fuel and the primary air in the gas mixing cavity.

[0050] like Figure 2 As shown, Figure 2 The schematic diagram of the structure of an ejector tube 22 provided in the embodiment of the present application, the burner 2 may further include an ejector tube 22, one end of which may be connected to the burner head 21 ( Figure 1 ) is connected, and the inside of the ejector tube 22 can be communicated with the gas mixing chamber. In this way, fuel gas and primary air can be introduced into the gas mixing chamber of the burner head 21 through the ejector tube 22.

[0051] Among them, refer to Figure 3 , Figure 3 This is one of the structural schematic diagrams of a burner 2 provided in an embodiment of the present application, wherein the ejector tube 22 has a gas inlet 221 and a gas outlet 222 arranged opposite to each other. The gas outlet 222 of the ejector tube 22 is connected to the gas mixing chamber of the burner head 21, and the gas inlet 221 of the ejector tube 22 enables the fuel to enter the ejector tube 22 and then flow into the gas mixing chamber of the burner head 21.

[0052] like Figure 4 As shown, Figure 4 The second structural schematic diagram of a burner 2 provided in an embodiment of the present application, the burner 2 may further include a fire cover 23. The fire cover 23 is provided on the burner head 21, and is provided with a gas outlet fire hole 231 connected to the gas mixing chamber. It can be understood that the gas mixing chamber formed inside the burner head 21 has an opening, and the fire cover 23 is provided on the opening of the gas mixing chamber so that the gas outlet fire hole 231 can be connected to the gas mixing chamber.

[0053] In this way, the primary air and fuel mixed in the gas mixing chamber of the burner 21 flow out from the gas outlet fire hole 231 of the fire cover 23 provided on the burner 21, are ignited to form a flame, and the flame heats the bottom of the pot for cooking by the user.

[0054] See also Figure 1The gas stove 100 provided in the present application further includes a panel 12, which is covered on the opening of the bottom shell 11 and is used to cover the mounting cavity 10 of the bottom shell 11. In this way, the panel 12 can prevent debris or food residues dropped during cooking from falling into the mounting cavity 10 of the bottom shell 11, thereby ensuring that other components arranged in the mounting cavity 10 are not damaged or contaminated, and further ensuring that the gas stove 100 can work normally.

[0055] In this case, if Figure 1 As shown, the panel 12 is also provided with an escape opening 120. The burner head 21 is arranged opposite to the escape opening 120 provided on the panel 12, so that the burner head 21 can be located within the opening range of the escape opening 120 of the panel 12. In this way, when the burner 2 burns fuel to generate flames, the panel 12 will not block the flames generated by the burner 2 burning fuel, ensuring that the burner 2 can work normally, so that the flames can heat the bottom of the pot, so that the user can cook.

[0056] As can be seen from the above, a gas stove 100 provided in the embodiment of the present application may include a bottom shell 11, a panel 12 and a burner 2 which is the core component of the gas stove 100. Figure 1 The burner 2 can be installed in the installation cavity 10 of the bottom shell 11, and then the installation cavity 10 of the bottom shell 11 is covered by the panel 12 to protect other components arranged in the installation cavity 10, ensure that the burner 2 and other components will not be damaged, and also protect the cooking utensils, thereby ensuring that the gas stove 100 can work normally.

[0057] In addition, if Figure 4 As shown, in order to ignite the primary mixed air flowing out of the gas outlet hole 231, the gas stove 100 provided in the embodiment of the present application further includes an ignition needle 24, which is installed on the burner head 21. At the same time, the burner 2 may also include a nozzle 14 ( Figure 4 The nozzle 14 may be disposed at one end of the ejector tube 22 away from the burner head 21. The gas may be injected into the ejector tube 22 through the nozzle 14, and the outside air may be introduced into the ejector tube 22 driven by the high-speed airflow near the nozzle 14 to form a gas-air mixture.

[0058] Since the gas stove 100 further includes an ignition needle 24 , the gas-air mixture in the gas mixing chamber can be ignited under the action of the ignition needle 24 after being ejected through the gas outlet fire hole 231 on the fire cover 23 , thereby heating the cookware.

[0059] During the use of the gas stove, frying and stir-frying are prone to produce oil smoke, stewing and boiling are prone to overflow, and the gas outlet holes 231 of the fire cover 23 are likely to be blocked by oil or overflowing liquid. In addition, the more gas outlet holes 231 of the fire cover 23 are made, the smaller the hole diameter is, and it is very inconvenient and difficult to clean them thoroughly by users alone.

[0060] For this reason, Figure 5 As shown, Figure 5 The second structural diagram of a gas stove 100 provided in the embodiment of the present application, the gas stove 100 provided in the embodiment of the present application further includes a fan assembly 25, the fan assembly 25 and the burner head 21 ( Figure 4 The fan assembly 25 has an air outlet, and the air outlet is communicated with the gas mixing chamber inside the furnace head 21.

[0061] The fan assembly 25 is used to blow external air into the air mixing chamber and blow the external air out through the air outlet fire hole 231. In addition, it can be understood that the fan assembly 25 also has an air inlet. External air can enter the fan assembly 25 through the air inlet of the fan assembly 25 and be blown out from the air outlet of the fan assembly 25.

[0062] Based on this, the gas stove 100 provided in the embodiment of the present application has the fan assembly 25 connected to the burner head 21, and the air outlet of the fan assembly 25 is connected to the gas mixing chamber inside the burner head 21. Figure 6 , Figure 6 A cross-sectional view of a burner 2 provided in an embodiment of the present application, when it is necessary to clean the gas outlet fire hole 231 on the fire cover 23, the fan assembly 25 ( Figure 5 ) The external air can be blown into the mixing chamber inside the burner head 21 through the air outlet, and blown out from the air outlet fire hole 231 connected to the mixing chamber. In this process, the residual stains in the air outlet fire hole 231 can be blown out, thereby cleaning the air outlet fire hole 231. The operation is simple and convenient, and no manual cleaning is required.

[0063] In addition, the wind generated by the fan assembly 25 cleans the air outlet fire hole 231, which can ensure the dryness of the interior of the mixing chamber, without the need to dry the mixing chamber, compared with cleaning the air outlet fire hole 231 with water.

[0064] As can be seen from the above, one end of the ejector tube 22 is connected to the furnace head 21, and the interior of the ejector tube 22 is connected to the gas mixing chamber. In some embodiments, one end of the fan assembly 25 can be connected to the other end of the ejector tube 22, and the air outlet of the fan assembly 25 is connected to the interior of the ejector tube 22.

[0065] In this way, the fan assembly 25 can introduce external air into the gas mixing chamber through the inside of the ejector tube 22, and blow it out from the gas outlet fire hole 231 connected to the gas mixing chamber, so as to clean the gas outlet fire hole 231. In addition, since the fan assembly 25 can be connected to the gas mixing chamber by means of the ejector tube 22, there is no need to provide a corresponding connecting structure on the burner head 21 to achieve the connection between the air inlet of the fan assembly 25 and the gas mixing chamber.

[0066] Of course, in other embodiments, the air outlet of the fan assembly 25 may also be directly connected to the gas mixing chamber of the burner head 21. In this case, a corresponding air inlet channel may be provided on the gas mixing chamber of the burner head 21, and the air outlet of the fan assembly 25 may be connected to the air inlet channel of the burner head 21, so that the external air is introduced into the gas mixing chamber through the air inlet channel.

[0067] like Figure 5 and Figure 7 As shown, Figure 7 This is one of the partial enlarged views of a gas stove 100 provided in an embodiment of the present application. The gas stove 100 may further include a gas pipeline 13 and at least one gas supply pipe 17. One end of the gas pipeline 13 may be connected to an external gas pipe. One end of the gas supply pipe 17 is connected to the gas pipeline 13, and the other end is connected to the ejector pipe 22. In this way, the gas may enter the interior of the gas pipeline 13 through the external gas pipe, and then enter the ejector pipe 22 through the gas supply pipe 17 connected to the gas pipeline 13, and finally enter the gas mixing chamber inside the burner 21.

[0068] It is understandable that the other end of the gas supply pipe 17 can be connected to the nozzle 14 , and the fuel gas is supplied into the ejector pipe 22 through the nozzle 14 .

[0069] In some embodiments, Figure 8 As shown, Figure 8 The second partial enlarged view of a gas stove 100 provided in the embodiment of the present application, the fan assembly 25 may include a fan 251. The fan 251 has the above-mentioned air outlet. Among them, the gas pipeline 13 ( Figure 5 ) can be connected to the air outlet of the fan 251. In this way, the fan 251 can blow the outside air into the gas pipeline 13 through the air outlet, and then enter the gas mixing chamber through the gas pipeline 13 and the air supply pipe 17.

[0070] In addition, in order to prevent the gas from flowing out through the fan 251, Fig. 9 As shown, Fig. 9 The third partial enlarged view of a gas stove 100 provided in an embodiment of the present application, the gas stove 100 may further include a first valve 15 and a second valve 16. The first valve 15 is disposed on the gas pipeline 13 and is close to one end of the gas pipeline 13. The second valve 16 is disposed on the gas pipeline 13 and is close to the other end of the gas pipeline 13.

[0071] The gas supply pipe 17 is located between the first valve 15 and the second valve 16. In this way, when the gas stove 100 is in normal use, the first valve 15 can be opened and the second valve 16 can be closed at the same time. In this way, the gas can enter the burner 21 ( Figure 5 ) of the gas mixing chamber, and at the same time, since the second valve 16 is closed, the gas will not leak through the fan 251.

[0072] Similarly, when the gas outlet fire hole 231 needs to be cleaned, the second valve 16 can be opened and the first valve 15 can be closed. In this way, the fan 251 can allow the outside air to enter the burner head 21 ( Figure 5 ) of the gas mixing chamber, and since the first valve 15 is closed, there will be no gas leakage.

[0073] In other embodiments, the fan 251 may not be connected to the other end of the gas pipeline 13. In this case, the gas stove 100 may include an air inlet pipeline, one end of which is connected to the gas outlet of the fan 251, and the other end of which is connected to the other end of the ejection pipe 22 and communicates with the interior of the ejection pipe 22. In this way, the air intake of the fan 251 and the intake of the gas are independent of each other and are not affected by each other.

[0074] In some embodiments, the gas stove 100 may further include a controller (not shown in the figure). The controller is electrically connected to the fan 251 and is used to control the operation or stop of the fan 251. In this way, the user can control the stop or operation of the fan 251 through the controller, and the operation is simpler or more convenient.

[0075] For example, Fig.10 As shown, Fig.10 The fourth partial enlarged view of a gas stove 100 provided in an embodiment of the present application, the burner 2 may further include a control panel 18, and the control panel 18 may have buttons. The control panel 18 may be electrically connected to the controller. In this way, the user may click a button on the control panel 18, so that the control panel 18 sends a signal to the controller, and the controller controls the fan 251 to stop or run after receiving the corresponding control signal.

[0076] Of course, in other embodiments, the fan 251 may also be directly electrically connected to the control panel 18. The buttons on the control panel 18 may control the power on or off of the fan 251, thereby realizing the operation or stop of the fan 251.

[0077] In some embodiments, the controller may also be electrically connected to the second valve 16 to control the opening or closing of the second valve 16. Thus, as mentioned above, when the user chooses to start the mode of cleaning the gas outlet fire hole 231, the user may click a button on the control panel 18, so that the control panel 18 sends a signal to the controller, and the controller may simultaneously control the operation or stop of the fan 251 and the opening or closing of the second valve 16 after receiving the corresponding control signal.

[0078] In this way, the linkage operation of the fan 251 and the second valve 16 can be controlled simultaneously only through the controller, making the overall operation process more intelligent and convenient.

[0079] Of course, in other embodiments, the controller may not be electrically connected to the second valve 16. At this time, the user may choose to manually open or close the second valve 16, and then control the opening or closing of the fan 251, which can also achieve the cleaning of the gas outlet fire hole 231.

[0080] Based on the above scheme, when controlling it to be electrically connected to the fan 251 and the second valve 16, in some embodiments, the controller can also be electrically connected to the first valve 15 to control the opening or closing of the first valve 15. As can be seen from the above, when the gas stove 100 is in a normal operating state, the fan 251 cannot be opened to clean the gas outlet fire hole 231, and the second valve 16 needs to be closed to prevent gas leakage. Since the controller is electrically connected to the first valve 15, the second valve 16 and the fan 251. In this way, the controller can control the operating states of the first valve 15, the second valve 16 and the fan 251 accordingly according to the operating state of the gas stove 100, so that the gas stove 100 can achieve different modes.

[0081] For example, when the gas stove 100 is in a normal operating state, the controller can control the first valve 15 to be in an open state, and control the second valve 16 and the fan 251 to be in a closed state. At this time, the gas can enter the inside of the ejector tube 22 through the gas pipeline 13 and the gas supply pipe 17, and then enter the gas mixing chamber of the burner head 21, and be ejected from the gas outlet fire hole 231 for combustion.

[0082] When the gas stove 100 is in a stopped state, the controller can control the first valve 15 to be in a closed state. When the user needs to clean the gas outlet fire hole 231, the user can click the button on the control panel 18 so that the controller receives the corresponding signal, and the controller can control the second valve 16 and the fan 251 to open, and keep the first valve 15 in a closed state. At this time, the fan 251 can send the external air to the inside of the ejector tube 22 through the gas pipeline 13 and the air supply pipe 17, and then enter the gas mixing chamber of the burner 21, and flow out from the gas outlet fire hole 231, clean the stains blocked in the gas outlet fire hole 231, and clean the gas outlet fire hole 231.

[0083] Of course, in other embodiments, the controller may not be electrically connected to the first valve 15. In this case, the user may manually control the opening or closing of the first valve 15 to perform corresponding adjustment work.

[0084] In some embodiments, the fan 251 may be a stepless variable speed fan. In this way, the user can operate the fan 251 at different speeds according to the blockage degree of the fire outlet hole 231, blow outside air of different wind speeds into the air mixing chamber, and then clean the fire outlet hole 231 to different degrees.

[0085] Of course, in other embodiments, the fan 251 may also be of other types, as long as it can achieve the effect of introducing external air to clean the air outlet fire hole 231, which will not be further explained here.

[0086] like Fig.10 As shown, in some embodiments, the gas stove 100 may further include a proportional valve 19. The proportional valve 19 is connected to one end of the air supply pipe 17 and is also connected to the gas pipeline 13, and the proportional valve 19 is located between the first valve 15 and the second valve 16. The proportional valve 19 can adjust the amount of air entering the air supply pipe 17.

[0087] In this way, when the gas stove 100 is in a normal operating state, the proportional valve 19 can control the gas intake to achieve the effect of adjusting the fire power of the gas stove 100. When the gas stove 100 is in a cleaning state, the proportional valve 19 can control the intake of external air, and different intakes can affect the cleaning effect of the gas outlet fire hole 231, achieving the effect of cleaning the gas outlet fire hole 231 to different degrees.

[0088] In some embodiments, Figure 5 As shown, the fan assembly 25 can be arranged in the bottom shell 11. The bottom shell 11 can provide an installation space for the fan assembly 25, and at the same time, the installation space inside the bottom shell 11 can be effectively utilized, and the installation of the fan assembly 25 is also relatively convenient.

[0089] In some embodiments, Fig.11 As shown, Fig.11 The schematic diagram of the structure of a bottom shell 11 provided in an embodiment of the present application is shown. The bottom shell 11 may include a bottom wall 111 and a side wall 112. The side wall 112 is located on one side of the bottom wall 111 and is arranged around the bottom wall 111. The bottom wall 111 and the side wall 112 enclose the above-mentioned installation cavity 10.

[0090] Among them, Fig.12 As shown, Fig.12 A partial enlarged view of a bottom shell 11 provided in an embodiment of the present application, the bottom wall 111 may be provided with an air inlet 1111, a fan assembly 25 ( Figure 5 ) can be arranged at the air inlet 1111 and connected to the bottom wall 111. In this way, the external wind can enter the installation cavity 10 through the air inlet 1111, and then blow into the furnace head 21 ( Figure 4 )'s mixing chamber, the overall air circulation is smoother.

[0091] Of course, in other embodiments, an air inlet may also be provided on the side wall 112. At this time, the fan assembly 25 may also introduce outside air into the installation cavity 10 through the air inlet on the side wall 112, and send it into the mixing cavity of the furnace head 21.

[0092] It is understandable that in order to ensure that the gas stove 100 can operate safely and stably, when the gas stove 100 is in a normal process, when the user clicks the button on the control panel 18 to start the fan 251 for cleaning, the controller can control the fan 251 and the second valve 16 to be non-responsive to prevent gas from leaking through the fan 251. Exemplarily, when the user clicks the button on the control panel 18 to start the cleaning mode, the control logic of the controller can be as follows: Fig.13 As shown, Fig.13 This is one of the control logic diagrams of a gas stove provided in an embodiment of the present application, and its control steps may include S100 to S300.

[0093] S100: The controller determines whether the gas stove is in an on-fire state.

[0094] S200: If the gas stove is in the on state, the controller cannot start the cleaning mode. At this time, the gas stove can be turned on normally for cooking.

[0095] Among them, Fig.14 As shown, Fig.14 This is the second control logic diagram of a gas stove provided in an embodiment of the present application, where step S200 may specifically include step S201.

[0096] S201, if the gas stove is in a firing state, the controller controls the first valve to be in an open state, and keeps the second valve and the fan in a closed state.

[0097] S300: If the gas stove is in the off state, the controller starts the cleaning mode, and the gas stove can clean the gas outlet.

[0098] Among them, Fig.15 As shown, Fig.15 This is a third control logic diagram of a gas stove provided in an embodiment of the present application. Step S300 may specifically include steps S301 to S302.

[0099] S301: The controller controls the fan to be in running state.

[0100] S302: The controller controls the first valve to close, and controls the second valve to open.

[0101] It is understandable that in order to ensure that the gas does not leak, when executing step S302, the first valve and the second valve may be initially in a closed state to prevent gas leakage. Alternatively, when the first valve is in an open state, the second valve may be initially in a closed state.

[0102] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0103] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
