Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gas stoves, in particular to a gas stove. Background Art
[0002] A gas stove refers to a kitchen appliance that uses liquefied petroleum gas, artificial gas, natural gas or other gases as fuel for heating.
[0003] The pot may be moved away during the use of the gas stove. When the flame is not used after the pot is moved away, the flame can be turned down by turning the knob to avoid energy waste. However, users usually do not turn down the flame when the pot is moved away. Currently, existing gas stoves detect the pot by setting a detection structure at the center of the burner to turn down the flame when the pot is detected to be moved away.
[0004] However, the above-mentioned detection structure is arranged in the middle position of the burner, which will affect the supplement of secondary air, thereby affecting the combustion effect of the burner, resulting in incomplete combustion and increasing the production of carbon monoxide. Utility Model Content
[0005] The utility model aims to provide a burner, aiming to solve the problem that the detection structure is arranged in the middle position of the burner and affects the secondary air supplement.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] The utility model provides a gas stove, comprising a shell, a burner, a panel, a fixing part and a capacitive sensor. The shell is formed with an installation cavity, and the installation cavity is used to install other components of the gas stove, such as a burner and a valve body. The burner is the core component of the gas stove, and the gas and air can be mixed and burned in a certain way through the burner. The panel cover is arranged on the shell to cover the installation cavity to protect the components in the installation cavity. The valve body is used to control the on and off of the gas in the burner and the size of the gas flow, so that the size of the flame can be controlled by the valve body.
[0008] The fixing member is located in the installation cavity and is connected to the panel. The capacitive sensor can be arranged in the accommodating cavity of the fixing member. In this way, the capacitive sensor can be installed in the installation cavity through the fixing member so as to facilitate the capacitive sensor detection.
[0009] When the capacitive sensor detects that the pot is away from the burner, for example, the pot placed above the burner is moved away from the area above the burner, the capacitive sensor detects that the pot is removed, and the capacitive sensor sends an electrical signal. The valve body electrically connected to the capacitive sensor controls the gas flow to reduce or cut off the gas, ensuring that the fire will not burn empty when there is no pot, saving energy.
[0010] When a pot is placed in the area above the burner, the capacitive sensor detects the presence of the pot, and the capacitive sensor sends an electrical signal. The valve body electrically connected to the capacitive sensor controls the gas flow to remain unchanged, and the fire power of the gas stove remains unchanged.
[0011] In addition, the capacitive sensor is used to detect whether the pot is close to or away from the burner. On the one hand, the capacitive sensor will not occupy the center position of the burner, so it will not affect the replenishment of secondary air. On the other hand, because the capacitive sensor is installed in the installation cavity of the shell through a fixing part and is located below the panel, the capacitive sensor can avoid direct exposure to the flame, and the capacitive sensor is less affected by the high temperature of the flame, thereby increasing the service life of the capacitive sensor.
[0012] In some embodiments of the present application, the gas stove further includes a shielding cover, which covers a side of the fixing member away from the panel and is disposed on the outside of the fixing member, and is used to shield the capacitive sensor from interference.
[0013] In some embodiments of the present application, the capacitive sensor includes a first capacitive sensor. The first capacitive sensor includes a circuit board and a sensing electrode. The circuit board is located in the accommodating cavity of the fixing member. The sensing electrode is disposed on the circuit board.
[0014] In some embodiments of the present application, the capacitive sensor includes a second capacitive sensor. The second capacitive sensor includes a circuit board, a transmitting electrode, and a receiving electrode. The circuit board is located in the accommodating cavity of the fixing member, the transmitting electrode and the receiving electrode are both arranged on the circuit board, and there is a gap between the receiving electrode and the transmitting electrode.
[0015] In some embodiments of the present application, a heat dissipation hole and a wiring hole are provided on the fixing member, wherein the heat dissipation hole is communicated with the accommodating cavity, and the wiring hole is communicated with the accommodating cavity.
[0016] In some embodiments of the present application, a glue groove is further provided on the fixing member, and the glue groove is provided on a side surface of the fixing member close to the panel, and the glue groove is arranged along the circumference of the accommodating cavity.
[0017] In some embodiments of the present application, a glue leakage hole is further provided on the fixing member, the glue leakage hole is located in the glue applying groove, and the glue leakage hole is connected to the glue applying groove.
[0018] In some embodiments of the present application, the gas stove further includes a controller, the controller is located in the installation cavity, and the controller is connected to one of the housing and the panel. There are multiple capacitive sensors, and the multiple capacitive sensors are all connected to the controller, and the controller is also connected to the valve body, and the capacitive sensor and the valve body are electrically connected through the controller.
[0019] In some embodiments of the present application, a plurality of capacitive sensors are spaced apart along the periphery of the combustor.
[0020] In some embodiments of the present application, the gas stove further includes a pot support. The pot support includes a base and a plurality of legs. The base is located on a side surface of the panel away from the installation cavity, and the base is arranged around the circumference of the avoidance hole. The plurality of legs are connected to a side surface of the base away from the installation cavity, and the plurality of legs are arranged at intervals along the circumference of the base. When there are multiple capacitive sensors, one capacitive sensor is arranged between two adjacent legs. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0051] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.
[0054] The present application provides a gas stove, such as Figure 1 As shown, the gas stove 100 may include a shell 11, a burner 12 and a panel 13. The shell 11 is formed with an installation cavity 10. The shell 11 is mainly used to install the relevant components of the gas stove 100, such as the burner, the gas control system, the electronic ignition component, etc. These components are arranged in the installation cavity 10 of the shell 11 of the gas stove. The burner 12 is arranged in the installation cavity 10 of the shell 11. The burner 12 is the core component of the gas stove 100, and the burner 12 can make the gas and air mix and burn in a certain way. The panel 13 is covered on the shell 11, and is used to cover the installation cavity 10. The panel 13 can protect the components arranged in the installation cavity 10.
[0055] Based on this, the panel 13 is further provided with an avoidance hole 130, and the burner 12 is located within the opening range of the avoidance hole 130. In this way, when the burner 12 burns fuel to generate flames, the panel 13 will not affect the normal operation of the burner 12.
[0056] Continue to refer to Figure 1 In addition to the above main components, the gas stove 100 also includes some indispensable components for realizing the gas stove 100. These components include a valve body 14, a knob 15, an ignition needle 16 and a thermocouple 17 (see Figure 2 ). The valve body 14 can control the on-off and flow rate of the gas. The valve body 14 is used to control the on-off of the gas in the burner 12 or to increase or decrease the flow rate of the gas. The knob 15 is connected to the valve body 14, so that the user can control the ignition and the size of the flame through the knob 15. When the knob 15 is turned, the ignition needle 16 will ignite the gas, and the gas will burn to form a flame. When the gas stove 100 is turned off, the thermocouple 17 will sense the flameout, so that the valve body 14 can be closed through relevant operations to stop the delivery of gas.
[0057] Continue to refer to Figure 1The gas stove 100 may further include some components to improve the gas stove 100. A knob mounting hole 150 is provided on the panel 13, and the knob 15 is installed in the knob mounting hole 150. In this case, in order to prevent the liquid accidentally overflowing from the pot from flowing into the mounting cavity 10 of the housing 11 from the knob mounting hole 150, the gas stove 100 may further include a knob waterproof ring 151, which is arranged at the knob mounting hole 150 to prevent the overflowing liquid from flowing into the interior of the housing 11 from the knob mounting hole 150. Similarly, the overflowing liquid may also flow into the interior of the housing 11 from the avoidance hole 130 on the panel 13. Therefore, a liquid pan 131 is provided at the avoidance hole 130, and the overflowing liquid can flow into the liquid pan 131. In order to further ensure that the overflowing liquid does not flow into the interior of the housing 11, a liquid pan waterproof ring 132 may be further provided on the periphery of the liquid pan 131 for further sealing.
[0058] like Figure 3 As shown, the gas stove 100 provided in the present application may further include a capacitive sensor 2, and the capacitive sensor 2 is located in the mounting cavity 10 of the housing 11. The capacitive sensor 2 is used to detect whether the pot is close to or away from the burner 12.
[0059] When the capacitive sensor 2 detects that the pot is away from the burner 12, for example, the pot placed above the burner 12 is moved away from the area above the burner 12, the capacitive sensor 2 detects that the pot is moved away, and the capacitive sensor 2 sends an electrical signal, and the valve body 14 electrically connected to the capacitive sensor 2 controls the gas flow to reduce or cut off the gas, ensuring that the fire will not burn when there is no pot, saving energy.
[0060] When a pot is placed in the area above the burner 12, the capacitive sensor 2 detects the presence of the pot, and the capacitive sensor 2 sends an electrical signal. The valve body 14 electrically connected to the capacitive sensor 2 controls the gas flow rate to remain unchanged, and the firepower of the gas stove 100 remains unchanged.
[0061] On this basis, in order to install the capacitive sensor 2 in the installation cavity 10, as shown in FIG. Figure 4 As shown, the gas stove 100 further includes a fixing member 20, and the fixing member 20 forms a receiving cavity 200. The fixing member 20 is located in the installation cavity 10, and the fixing member 20 is connected to the panel 13. For example, Figure 5 As shown, the side surface of the fixing member 20 with the accommodating cavity 200 is connected to the panel 13. Based on this, the capacitive sensor 2 can be arranged in the accommodating cavity 200 of the fixing member 20. In this way, the capacitive sensor 2 can be installed in the installation cavity 10 through the fixing member 20 so that the capacitive sensor 2 can detect.
[0062] In addition, it should be noted that the capacitive sensor 2 is arranged along the periphery of the burner 12 (see Figure 3 ). On the one hand, the capacitive sensor 2 will not occupy the center position of the burner 12, so as not to affect the supplement of secondary air. On the other hand, since the capacitive sensor 2 is installed in the installation cavity 10 of the housing 11 through the fixing member 20 and is located below the panel 13. In this way, the capacitive sensor 2 can avoid being directly exposed to the flame, and the influence of the high temperature of the flame on the capacitive sensor 2 is reduced, thereby improving the service life of the capacitive sensor 2.
[0063] The working principle of the capacitive sensor 2 is mainly based on the electric field formed between the object and the capacitive sensor 2. When an object approaches or contacts the capacitive sensor 2, the object changes the electric field distribution of the capacitive sensor 2, thereby causing the capacitance on the capacitive sensor 2 to change. By measuring the change in capacitance, the capacitive sensor 2 can determine the relevant physical quantity between the capacitive sensor 2 and the object being measured, such as the distance between the capacitive sensor 2 and the object being measured.
[0064] The gas stove 100 provided in the present application may further include a shielding cover. The shielding cover is located on a side of the fixing member 20 away from the panel 13, and the shielding cover is arranged outside the fixing member 20, and the shielding cover is used to shield the interference received by the capacitive sensor 2. In this way, when the capacitive sensor 2 is arranged in the installation cavity 10, the influence of other components installed in the installation cavity 10 on the capacitive sensor 2 can be shielded by the shielding cover.
[0065] In some embodiments of the present application, Figure 6 As shown, the capacitive sensor 2 includes a first capacitive sensor 21. The first capacitive sensor 21 includes a circuit board 4. The circuit board 4 is located in the accommodating cavity 200 of the fixing member 20. The first capacitive sensor 21 also includes a sensing electrode 210, which is disposed on the circuit board 4. It should be noted that the first capacitive sensor 21 may also include other components, for example, a covering layer, which covers the side of the circuit board 4 where the sensing electrode 210 is disposed, so as to protect the sensing electrode 210.
[0066] The first capacitive sensor 21 is arranged along the periphery of the burner 12. When the pot moves, the pot will cause the capacitance of the first capacitive sensor 21 to change. For example, when the pot is placed above the burner 12, the pot gradually approaches the first capacitive sensor 12. The distance between the pot and the sensing electrode 210 gradually decreases, the capacitance of the sensing electrode 210 decreases, the first capacitive sensor 21 detects the decrease in capacitance and sends an electrical signal, and the valve body 14 electrically connected to the first capacitive sensor 21 keeps the gas flow unchanged.
[0067] When the pot is removed from the area above the burner 12, the capacitance of the sensing electrode 210 is restored, the first capacitive sensor 21 detects the change in capacitance and sends an electrical signal, and the valve body 14 electrically connected to the first capacitive sensor 21 reduces the flow of gas, thereby reducing the flame and avoiding high flame burning when there is no pot.
[0068] In other embodiments of the present application, Figure 7 As shown, the capacitive sensor 2 includes a second capacitive sensor 22. The second capacitive sensor 22 includes a circuit board 4, and the circuit board 4 is located in the accommodating cavity 200 of the fixing member 20.
[0069] The second capacitive sensor 22 further includes a transmitting electrode 221 and a receiving electrode 222. Both the transmitting electrode 221 and the receiving electrode 222 are arranged on the circuit board 4, and there is a gap between the receiving electrode 221 and the transmitting electrode 222, and the receiving electrode 221 and the transmitting electrode 222 are arranged at a gap to ensure their normal operation.
[0070] The second capacitive sensor 22 uses mutual capacitance sensing, the transmitting electrode 221 provides a digital voltage, and measures the charge received on the pin of the receiving electrode 222. The charge received on the receiving electrode 222 is proportional to the mutual capacitance between the transmitting electrode 221 and the receiving electrode 222. When there is an object between the transmitting electrode 221 and the receiving electrode 222, the mutual capacitance decreases, so the charge received on the receiving electrode 222 also decreases. Therefore, it is possible to detect whether there is an object between the transmitting electrode 221 and the receiving electrode 222 by detecting the charge on the receiving electrode 222.
[0071] Based on this, the second capacitive sensor 22 is arranged along the periphery of the burner 12. When the pot is placed in the upper area of the burner 12, the mutual capacitance between the transmitting electrode 221 and the receiving electrode 222 will be reduced. When the pot is removed from the upper part of the burner 12, the mutual capacitance will no longer be reduced, so that the charge received on the receiving electrode 222 will also increase. The second capacitive sensor 22 detects the increase in the charge received on the receiving electrode 222 and sends an electrical signal. The valve body 14 electrically connected to the second capacitive sensor 22 controls the gas flow rate to reduce the flame, so as to avoid a large fire burning when there is no pot.
[0072] It is easy to understand that during the use of the gas stove 100, while the gas combustion heats the bottom of the cookware, the heat generated by the gas combustion will also radiate to the surface of the panel 13, and the temperature of the panel 13 will also increase to a certain extent. Since the fixing member 20 is connected to the panel 13, when the fixing member 20 forms a receiving cavity 200, the temperature in the receiving cavity 200 will also increase as the temperature of the panel 13 increases. In addition, the electronic components printed on the circuit board 4 will also generate a certain amount of heat during operation.
[0073] Therefore, in order to dissipate the heat inside the accommodating cavity 200, Figure 8 As shown, the fixing member 20 is provided with a heat dissipation hole 201 . The heat dissipation hole 201 is communicated with the accommodating cavity 200 of the fixing member 20 .
[0074] In this way, the heat conducted to the accommodating cavity 200 through the panel 13, or the heat generated by other electronic components on the circuit board 4 when working, can be dissipated through the heat dissipation holes 201 connected to the accommodating cavity 200. This ensures that the temperature in the accommodating cavity 200 will not be too high, thereby ensuring the detection accuracy and service life of the inductive sensor 21.
[0075] For example, in some embodiments of the present application, see Fig. 9 The heat dissipation hole 201 may be a circular through hole and penetrate the fixing member 20, so that the accommodating cavity 200 can communicate with the outside of the fixing member 20 through the heat dissipation hole 201. Thus, the heat in the accommodating cavity 200 can be discharged from the accommodating cavity 200 through the heat dissipation hole 201.
[0076] Furthermore, the number of the heat dissipation holes 201 can be multiple, and the multiple heat dissipation holes 201 can be evenly opened on the fixing member 20 (see Fig. 9 ). The uniform arrangement of the plurality of heat dissipation holes 201 can improve the efficiency of heat dissipation in the heat dissipation holes 201 .
[0077] For example, in other embodiments of the present application, see Fig.10 The heat dissipation hole 201 may be rectangular, for example, the heat dissipation hole 201 may be rectangular. Further, the number of the heat dissipation holes 201 may be multiple, and multiple rectangular heat dissipation holes 201 are arranged at intervals on the fixing member 20. The uniform arrangement of multiple rectangular heat dissipation holes 201 can improve the efficiency of heat dissipation in the heat dissipation holes 201.
[0078] Another example Fig.11 As shown, the shape of the heat dissipation hole 201 can also be a square. Further, the number of the heat dissipation holes 201 can be multiple, and multiple square heat dissipation holes 201 are arranged at intervals on the fixing member 20. The uniform arrangement of multiple square heat dissipation holes 201 can improve the efficiency of heat dissipation in the heat dissipation holes 201.
[0079] On this basis, in order to enable the circuit board 4 disposed in the accommodating cavity 200 to be electrically connected to the valve body 14 and other control panels. Fig.12 As shown, the fixing member 20 is further provided with a wiring hole 202 . The wiring hole 202 is communicated with the accommodating cavity 200 of the fixing member 20 .
[0080] In this way, the wires of the circuit board 4 disposed in the accommodating cavity 200 can pass through the wiring holes 202 from the accommodating cavity 200 to the outside of the accommodating cavity 200, so as to supply power to the circuit board 4 disposed in the accommodating cavity 200 through the wires, and transmit the electrical signals sent by the circuit board 4 to the valve body 14 electrically connected thereto.
[0081] In the case where the fixing member 20 is formed with the accommodating cavity 200, as Fig.13 As shown, the fixing member 20 is also provided with a glue groove 203. The glue groove 203 is provided on a side surface of the fixing member 20 close to the panel 13 (not shown in the figure). The glue groove 203 is arranged along the outer side of the accommodating cavity 200. In addition, there is a certain interval between the glue groove 203 and the accommodating cavity 200, and the glue groove 203 and the accommodating cavity 200 are not connected.
[0082] In this way, glue can be applied to the glue groove 203, and after the glue is applied, the side of the fixing member 20 with the glue groove 203 is in contact with the panel 13, and then the fixing member 20 is pressed to ensure that the glue in the glue groove 203 is in full contact with the panel 13 to ensure a firm bond. Since the panel 13 is usually made of glass, silicone glue can be used when applying glue to the glue groove 203.
[0083] In addition, since there is a certain interval between the glue groove 203 and the accommodating cavity 200, and the glue groove 203 and the accommodating cavity 200 are not connected, it is possible to prevent the glue from flowing from the glue groove 203 into the accommodating cavity 200 during the glue coating process, ensuring that the circuit board 4 and the fixing member 20 will not be adhered to each other due to glue.
[0084] For example, see Fig.13 There are two glue grooves 203 , and the two glue grooves 203 are opened on one side surface of the fixing member 20 where the accommodating cavity 200 is opened, and the two glue grooves 203 are opened on two opposite sides of the accommodating cavity 200 , and the two glue grooves 203 are not connected to the accommodating cavity 200 .
[0085] In this way, silicone glue can be applied to the two glue grooves 203, and after applying the glue, the side of the fixing member 20 with the glue groove 203 is in contact with the panel 13, and then the fixing member 20 is pressed to ensure that the glue in the glue groove 203 is in full contact with the panel 13 to ensure a firm bond.
[0086] Another example Fig.14 As shown, the number of the glue grooves 203 can also be four, and the four glue grooves 203 are all opened along the side surface of the fixing member 20 where the accommodating cavity 200 is opened, and the four glue grooves 203 are opened along the outer periphery of the accommodating cavity 200.
[0087] Similarly, silicone glue can be applied to the four glue grooves 203, and after applying the glue, the side of the fixing member 20 with the glue groove 203 is in contact with the panel 13, and then the fixing member 20 is pressed to ensure that the glue in the glue groove 203 is in full contact with the panel 13 to ensure a firm bond. Compared with two glue grooves 203, four glue grooves 203 can further improve the stability of the connection between the fixing member 20 and the panel 13.
[0088] Further, on the basis of the four glue-applying grooves 203, the four glue-applying grooves 203 can also be connected, such as Fig.15 As shown, the glue groove 203 is in the shape of a "mouth", and the "mouth"-shaped glue groove 203 is opened on the outer peripheral side of the accommodating cavity 200. Similarly, silica sol is applied to the "mouth"-shaped glue groove 203, and then the fixing member 20 is pressed on the panel 13, so that the fixing member 20 and the panel 13 are adhered by the silicone glue.
[0089] As can be seen from the above, by opening a glue groove 203 on the fixing member 20 and applying silicone glue (or other adhesive) in the glue groove 203, the fixing member 20 is connected to the panel 13 through the silicone glue. Fig.16 As shown, a glue leakage hole 204 is also provided on the fixing member 20. The glue leakage hole 204 is located in the glue groove 203, and the glue leakage hole 204 runs through the glue groove 203.
[0090] In this way, silicone glue is applied to the glue groove 203 of the fixing member 20, and when the fixing member 20 is pressed on the panel 13, the excess silicone glue in the glue groove 203 will be squeezed out from the glue leakage hole 204. The silicone glue leaking from the glue leakage hole 204 will be columnar after drying, and the dried columnar silicone glue can prevent the fixing member 20 from falling off.
[0091] For example, Fig.16 As shown, a plurality of glue leaking holes 204 may be provided at intervals in a glue groove 203. The plurality of glue leaking holes 204 are evenly provided in the glue groove 203, so that when the fixing member 20 is pressed toward the panel 13, the silicone glue in the glue groove 203 can be evenly squeezed out from the plurality of glue leaking holes 204 arranged at intervals. The silicone glue squeezed out from the glue leaking holes 204 forms a plurality of columnar silicone glues after drying, and the dried columnar silicone glues can make the connection between the fixing member 20 and the panel 13 through the silicone glue more reliable.
[0092] In some embodiments of the present application, Fig.17 As shown, the gas stove 100 may further include a controller 5, which is located in the mounting cavity 10 of the housing 11 (see Figure 3 ). The controller 5 is connected to one of the housing 11 and the panel 13. Based on this, the capacitive sensor 2 and the valve body 14 can be electrically connected through the controller 5.
[0093] There are multiple capacitive sensors 2, and all of the multiple capacitive sensors 2 are electrically connected to the controller 5. Furthermore, the controller 5 is also electrically connected to the valve body 14. The capacitive sensor 2 is electrically connected to the valve body 14 through the controller 5.
[0094] In this way, when any one of the plurality of capacitive sensors 2 detects that the pot is moved away from the upper area of the burner 12, an electrical signal can be sent to the controller 5, and then the valve body 14 reduces the gas flow rate to reduce the flame.
[0095] On this basis, when there are multiple capacitive sensors 2, the multiple capacitive sensors 2 are arranged at intervals along the outer periphery of the burner 12. In this way, when any one of the multiple capacitive sensors 2 detects that the pot has moved, the valve body 14 can be controlled to adjust the gas flow rate. This can avoid the capacitive sensor 2 being unable to detect the movement of the pot due to the size of the pot or the placement of the pot, thereby improving the detection accuracy.
[0096] Exemplarily, when there are multiple capacitive sensors 2, they may be two first capacitive sensors 21 and two second capacitive sensors 22. In this case, Fig.18 As shown, the first capacitive sensor 21 and the second capacitive sensor 22 can be arranged alternately. When any one of the two first capacitive sensors 21 and the two second capacitive sensors 22 detects the presence of a pot, it is considered that the pot exists. When none of the four sensors detects the pot, it is considered that the pot does not exist, and the valve body 14 controls the flame to reduce. This avoids the occurrence of false detection when the pot is too small.
[0097] like Fig.19 As shown, the gas stove 100 provided in the present application may also include a pot support 6. The pot support 6 includes a base 61. The base 61 is located on the panel 13 away from the installation cavity 10 (see Figure 1 ) side surface. And the base 61 is around the avoidance hole 130 (see Figure 1 ) is arranged circumferentially. In this way, it can be ensured that the base 61 will not interfere with the burner 12.
[0098] The pot support 6 further includes a plurality of legs 62 . The plurality of legs 62 are connected to a side surface of the base 61 away from the mounting cavity 10 . The plurality of legs 62 are arranged at intervals along the circumference of the base 61 .
[0099] In this way, the pot can be placed on one end of the plurality of legs 62 away from the base 61, and the plurality of legs 62 can provide support for the pot, so that the pot can be stably placed in the upper area of the burner 12 for easy cooking.
[0100] The above-mentioned legs 62 are usually made of metal. In this case, when there are multiple capacitive sensors 2, such as Fig. 20As shown, a capacitive sensor 2 is disposed between two adjacent legs 62. It should be noted that a capacitive sensor 2 is disposed between two adjacent legs 62 refers to the positional relationship between the projections of multiple legs 62 on the panel 13 and the projections of multiple capacitive sensors 2 on the panel 13. That is, the projection of a capacitive sensor 2 is located between the projections of two adjacent legs 62.
[0101] In this way, the capacitive sensor 2 can avoid the support foot 62 and will not be affected by the support foot 62, thereby ensuring the accuracy of detection.
[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.
