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 valve body and a detection component. The shell is formed with an installation cavity, and the installation cavity is used to install other components of the gas stove, such as the burner and the 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 through the valve body.

[0008] The detection component is arranged in the installation cavity, connected to the panel, and also electrically connected to the valve body. The detection component is arranged along the periphery of the burner and is used to detect whether the pot is close to or away from the burner.

[0009] When the detection component detects that the pot is away from the burner, the detection component sends an electrical signal, and the valve body electrically connected to the detection component controls the gas flow to reduce or cut off the flow of gas. Thus, when the user moves the pot away from the burner, the flame is reduced, ensuring that the flame will not burn when there is no pot, thus saving energy.

[0010] When a pot is placed in the area above the burner, the detection component detects the presence of the pot, the detection component sends an electrical signal, and the valve body electrically connected to the detection component controls the gas flow to remain unchanged, so that the fire power of the gas stove remains unchanged.

[0011] Since the detection assembly is arranged along the periphery of the burner, the detection assembly does not occupy the center position of the burner. In this way, the detection assembly does not affect the replenishment of secondary air, thereby ensuring that the gas can be fully burned. In addition, since the detection assembly is far away from the center position of the burner and is arranged in the installation cavity of the shell, it is not directly exposed to the flame. Therefore, the detection assembly is less affected by the high temperature of the flame, which increases the service life of the detection assembly.

[0012] In some embodiments of the present application, the detection assembly includes a fixing member and an inductive sensor, wherein the fixing member is installed in the installation cavity, and the inductive sensor is located on a side of the fixing member close to the panel and connected to the fixing member.

[0013] In some embodiments of the present application, the detection component includes a fixing member and a circuit board. The fixing member is formed with a receiving cavity, the fixing member is installed in the installation cavity, and is connected to the panel. The circuit board is located in the receiving cavity, and an inductor coil is printed on the circuit board.

[0014] 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.

[0015] In some embodiments of the present application, a glue groove is further provided on the fixing member, 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 outer side of the accommodating cavity.

[0016] 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 injection groove, and the glue leakage hole runs through the glue injection groove.

[0017] In some embodiments of the present application, the detection assembly includes a fixing member and a metal proximity sensor. The fixing member is installed in the installation cavity, and the fixing member has a fixing portion and a mounting portion. One side surface of the fixing portion is connected to the housing, and the other side surface of the fixing portion is connected to the mounting portion, and the mounting portion forms an installation space. The metal proximity sensor is located in the installation space.

[0018] In some embodiments of the present application, a first through hole is formed on the fixing portion, and a second through hole is formed on the mounting portion, and the second through hole is connected to the first through hole.

[0019] In some embodiments of the present application, there are multiple detection assemblies, and the multiple detection assemblies are arranged at intervals along the periphery of the burner.

[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 a plurality of legs are arranged around the circumference of the avoidance hole to connect to the 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 detection components, one detection component is arranged between two adjacent legs. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0049] 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.

[0052] The present application provides a gas stove, such as Figure 1As 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.

[0053] 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.

[0054] 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, a thermocouple 17, etc. (see Figure 2 ). The valve body 14 can control the on-off and flow rate of the gas, and the valve body 14 is used to control the on-off of the gas in the burner 12. The knob 15 is connected to the valve body 14, so that the user can control the ignition and the flame size 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.

[0055] Continue to refer to Figure 1 The gas stove 100 may also include some components to improve the gas stove 100. Figure 1 As shown, 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.

[0056] like Figure 3 As shown, the gas stove 100 provided in the present application may further include a detection assembly 2, which is disposed in the mounting cavity 10 of the housing 11. The detection assembly 2 is connected to the panel 13, and the detection assembly 2 is also electrically connected to the valve body, and the detection assembly 2 is disposed along the periphery of the burner 12.

[0057] The detection assembly 2 is used to detect whether the pot is close to or away from the burner 12. When the detection assembly 2 detects that the pot is away from the burner 12, the detection assembly 2 sends an electrical signal, and the valve body 14 electrically connected to the detection assembly 2 controls the flow of gas to reduce or cut off the flow of gas. Therefore, when the user removes the pot from the burner 12, the flame is reduced, ensuring that the fire will not burn when there is no pot, saving energy.

[0058] When a pot is placed in the area above the burner 12, the detection component detects the presence of the pot, the detection component 2 sends an electrical signal, and the valve body 14 electrically connected to the detection component 2 controls the gas flow to remain unchanged, so that the firepower of the gas stove 100 remains unchanged.

[0059] As can be seen from the above, the detection assembly 2 is arranged along the periphery of the burner 12 (see Figure 3 ). In this way, the detection component 2 will not occupy the center position of the burner 12, and the detection component 2 will not affect the supplement of secondary air, thereby ensuring that the gas can be fully burned. In addition, since the detection component is far away from the center position of the burner 12, but is arranged in the installation cavity 10 of the shell 11, it is not directly exposed to the flame. Therefore, the detection component 2 is less affected by the high temperature of the flame, which increases the service life of the detection component 2.

[0060] Next, the above detection component 2 is further described. Figure 4 As shown, the detection assembly 2 includes a fixing member 20. The fixing member 20 is installed in the installation cavity 10 of the housing 11.

[0061] The detection assembly 2 also includes an inductive sensor 21. Figure 5 The inductive sensor 21 is located on a side of the fixing member 20 close to the panel 13 , and the inductive sensor 21 is connected to the fixing member 20 .

[0062] In this way, the inductive sensor 21 can be installed in the installation cavity 10 of the shell 11 through the fixing member 20, thereby realizing the function of detecting the cookware.

[0063] The working principle of the inductive sensor 21 is electromagnetic induction. The measured non-electrical quantity such as displacement, pressure, etc. is converted into the change of coil self-inductance or mutual inductance, and then converted into the change of voltage or current by the measuring circuit for output.

[0064] See also Figure 4and Figure 5 In some embodiments of the present application, the fixing member 20 is formed with a receiving cavity 200. The fixing member 20 is installed in the installation cavity 10 of the housing 11 and connected to the panel 13.

[0065] In some embodiments of the present application, Figure 6 As shown, the detection component 2 may further include a printed circuit board (PCB) 210 , which is located in the accommodating cavity 200 and has an inductor 211 printed on it.

[0066] The inductor 211 emits a high-frequency electromagnetic field when in operation. Since the inductor 211 is arranged around the outer side of the burner 12, eddy currents will be generated at the bottom of the metal cookware when the metal cookware is located within a certain range above the burner 12. When the eddy currents flow in the metal cookware, a reverse electromagnetic field will be generated, which will cause the effective inductance in the inductor 211 to decrease.

[0067] When the metal cookware is not in the area above the burner 12 and is not within the range of the electromagnetic field, the magnetic field emitted by the inductor 211 cannot form an effective eddy current at the bottom of the metal cookware. Therefore, whether the metal cookware is placed above the burner 12 can be detected by detecting the change in inductance.

[0068] In addition, it should be noted that the tiny eddy current generated at the bottom of the metal cookware in the above manner does not affect the heating state of the metal cookware.

[0069] The inductor 211 can generate a high-frequency electromagnetic field. The detection component 2 may also include a control chip 212. Figure 7 The control chip 212 is electrically connected to the inductor 211, and the control chip 212 is also electrically connected to the valve body 14. The control chip 212 may be a Cypress PSoC 4700 chip, which can detect the change of the effective inductance in the inductor 211, and then control the opening of the valve body 14 according to the change of the inductance.

[0070] For example, when the metal pot placed in the area above the burner 12 is removed, the metal pot leaves the magnetic field emitted by the inductor 211, and no effective eddy current is formed at the bottom of the metal pot. As a result, the reverse electromagnetic field generated by the eddy current also disappears, and the effective inductance of the inductor 210 that is not affected by the reverse electromagnetic field is restored. The control chip 212 detects the change in inductance and controls the valve body 14 to adjust the gas flow rate, so that the flame is reduced to avoid empty burning.

[0071] 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 inductor coil printed on the PCB will also generate a certain amount of heat during operation.

[0072] Therefore, in order to dissipate the heat inside the accommodating cavity 200, Figure 8 As shown, a heat dissipation hole 2001 is provided on the fixing member 20. The heat dissipation hole 2001 is communicated with the accommodating cavity 200 of the fixing member 20.

[0073] In this way, the heat conducted into the accommodating cavity 200 through the panel 13 or the heat generated by the inductive sensor 21 itself when working can be dissipated through the heat dissipation holes 2001 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.

[0074] For example, in some embodiments of the present application, see Figure 8 The heat dissipation hole 2001 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 2001. Thus, the heat in the accommodating cavity 200 can be discharged from the accommodating cavity 200 through the heat dissipation hole 2001.

[0075] Furthermore, the number of the heat dissipation holes 2001 can be multiple, and the multiple heat dissipation holes 2001 can be evenly arranged on the fixing member 20. Evenly arranging the multiple heat dissipation holes 2001 can improve the efficiency of heat dissipation in the heat dissipation holes 2001.

[0076] For example, in other embodiments of the present application, see Fig. 9 The heat dissipation hole 2001 may be rectangular, for example, the heat dissipation hole 2001 may be rectangular. Further, the number of the heat dissipation holes 2001 may be multiple, and multiple rectangular heat dissipation holes 2001 are arranged at intervals on the fixing member 20. The uniform arrangement of multiple rectangular heat dissipation holes 2001 can improve the efficiency of heat dissipation in the heat dissipation holes 2001.

[0077] The shape of the heat dissipation hole 2001 can also be square. Further, the number of the heat dissipation holes 2001 can be multiple, and multiple square heat dissipation holes 2001 are arranged at intervals on the fixing member 20. The uniform arrangement of multiple square heat dissipation holes 2001 can improve the efficiency of heat dissipation in the heat dissipation holes 2001.

[0078] On this basis, in order to enable the PCB disposed in the accommodating cavity 200 to be electrically connected to the valve body 14 and other control panels. Fig.10 As shown, a wiring hole 2002 is also provided on the fixing member 20. The wiring hole 2002 is communicated with the accommodating cavity 200 of the fixing member 20.

[0079] In this way, the wires of the PCB disposed in the accommodating cavity 200 can pass through the wiring holes 2002 from the accommodating cavity 200 to the outside of the accommodating cavity 200, so as to power the PCB disposed in the accommodating cavity 200 through the wires, and transmit the electrical signals emitted by the PCB to the valve body 14 electrically connected thereto.

[0080] In the case where the fixing member 20 is formed with the accommodating cavity 200, as Fig.11 As shown, a glue groove 203 is also provided on the fixing member 20. The glue groove 203 is provided on a side surface of the fixing member 20 close to the panel 13. 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.

[0081] 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.

[0082] In addition, since there is a certain distance 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 PCB and the fixing member 20 will not be adhered to each other due to glue.

[0083] For example, see Fig.11 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 .

[0084] 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.

[0085] Another example Fig.12As 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.

[0086] 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.

[0087] Further, on the basis of the four glue-applying grooves 203, the four glue-applying grooves 203 can also be connected, such as Fig.13 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.

[0088] 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.14 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.

[0089] 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.

[0090] For example, Fig.14 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.

[0091] like Fig.15As shown, in some other embodiments of the present application, the detection assembly 2 may further include a fixing member 20. The fixing member 20 is installed in the installation cavity 10 of the housing 11, and the fixing member 20 has a fixing portion 201, and one side surface of the fixing portion 201 is connected to the housing 11.

[0092] See also Fig.15 The fixing member 20 also has a mounting portion 202, and the mounting portion 202 is connected to the other side surface of the fixing portion 201. Fig.16 As shown, the mounting portion 202 is formed with a mounting space 2020 .

[0093] See also Fig.15 and Fig.16 The detection assembly 2 further includes a metal proximity sensor 22, which can be installed in the installation space 2020. The mounting portion 202 can support the metal proximity sensor 22, and the mounting portion 202 can also play a limiting role to ensure that the metal proximity sensor 22 will not be displaced in the installation cavity 10.

[0094] The metal proximity sensor 22 utilizes an alternating magnetic field generated by a vibrator. When a metal target approaches the magnetic field and reaches the sensing distance, eddy currents are generated in the metal target, which causes the vibration of the vibrator to attenuate, so that the vibrator of the proximity sensor stops vibrating.

[0095] Based on this, when the metal pot is placed on the burner 12, eddy currents will be generated inside the metal pot, which will cause the vibration of the vibrator to attenuate, so that the vibrator close to the sensor stops vibrating.

[0096] At the same time, the proximity sensor sends an electrical signal and transmits it to the valve body 14 electrically connected thereto, so that the valve body 14 controls the flow rate of the gas to decrease, thereby reducing the flame, avoiding empty burning, and reducing gas waste.

[0097] In the process of removing the pot from the burner 12, as the pot moves away from the burner 12, the eddy current generated inside the pot gradually decreases. As a result, the vibration is enhanced, so that the vibrator of the proximity sensor vibrates. At the same time, the proximity sensor sends an electrical signal and transmits it to the valve body 14 electrically connected thereto, so that the valve body 14 controls the flow of the gas to increase, so that the flame increases.

[0098] In addition, it should be noted that the panel 13 is usually made of glass, and no eddy current will be generated in the panel 13 , and thus the panel 13 will not affect the detection of the inductive proximity sensor.

[0099] like Fig.16As shown, a first through hole 2011 is formed on the fixing portion 201. A second through hole 2021 is formed on the mounting portion 202. The second through hole 2021 is connected to the first through hole 2011, so that the wire of the metal proximity sensor 22 disposed in the mounting space 2020 can pass through the second through hole 2021 and the first through hole 2011 in sequence, and then be electrically connected to the valve body 14.

[0100] In some embodiments of the present application, there may be multiple detection assemblies 2, and the multiple detection assemblies 2 are arranged at intervals along the outer periphery of the burner 12. And the multiple detection assemblies 2 are electrically connected to the valve body 14. In this way, when any one of the multiple detection assemblies 2 detects that the pot has moved, the valve body 14 can be controlled to adjust the opening. This can avoid the detection assembly 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.

[0101] Exemplarily, when there are multiple detection components 2, the inductive sensor 21 in the detection component 2 can be a circuit board 210 printed with an inductor 211. In this case, the fixing member 20 in the detection component 2 is formed with a accommodating cavity 200. Further, the fixing member 20 provided with the circuit board 210 is arranged at intervals along the outer periphery of the burner 12. In this way, when the effective inductance in any one of the inductor 211 in the multiple detection components 2 changes, the control chip 212 can detect this change, and then adjust the gas flow in the control valve body 14. For example, when the metal pot is moved away from the top of the burner 12, the effective inductance in the inductor 211 will increase, and the control chip 212 detects that the effective inductance in the inductor 211 increases, and then controls the valve body 14 to reduce the opening, so that the gas flow is reduced, thereby reducing the flame, and achieving the purpose of moving the pot to a low fire.

[0102] like Fig.17 As shown, the gas stove 100 provided in the present application may further include a pot support 4. The pot support 4 includes a base 41. The base 41 is located on a side surface of the panel 13 away from the installation cavity 10. The base 41 is arranged around the circumference of the avoidance hole 130. In this way, it can be ensured that the base 41 will not interfere with the burner 12.

[0103] The pot support 4 further includes a plurality of legs 42 . The plurality of legs 42 are connected to a side surface of the base 41 away from the mounting cavity 10 . The plurality of legs 42 are arranged at intervals along the circumference of the base 41 .

[0104] In this way, the pot can be placed on the end of the multiple legs 42 away from the base 41, and the multiple legs 42 can provide support for the pot, so that the pot can be stably placed in the upper area of ​​the burner 12 for cooking.

[0105] The above-mentioned legs 42 are usually made of metal. In this case, when there are multiple detection components 2, such as Fig.18 As shown, one detection component 2 is disposed between two adjacent legs 42. It should be noted that one detection component 2 is disposed between two adjacent legs 42 refers to the positional relationship between the projections of multiple legs 42 on the panel 13 and the projections of multiple detection components 2 on the panel 13. That is, the projection of one detection component 2 is located between the projections of two adjacent legs 42.

[0106] In this way, the detection component 2 can avoid the support foot 42 and will not be affected by the support foot 42, thereby ensuring the accuracy of the detection.

[0107] 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.

[0108] 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.
