DETAILED DESCRIPTION

[0035] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0036] Gas stoves, as a key component of kitchen appliances, are commonly installed in kitchens and are a common household appliance used in daily cooking. The safety of gas stoves is a major concern in this field. Gas stoves are prominently placed in kitchens, and existing gas stoves can be turned on simply by manually igniting them. However, children can easily approach or touch a gas stove without supervision, leading to dangerous behaviors in the kitchen, such as playing with fire. This poses a safety hazard to gas stoves.

[0037] Based on this, the embodiment of the present invention provides a gas stove, see Figure 1 The schematic diagram of the structure of a gas stove shown includes a gas stove body 01, on which a burner 02, a gas collection device 03, a gas knob 04, and a controller 05 are installed; the burner 02 is connected to an igniter 06 and a gas pipe 07, respectively, and a control valve 08 is installed on the gas pipe 07; the gas knob 04 is connected to the igniter 06 and the control valve 08, respectively; the collection device 03 and the gas knob 04 are connected to the controller 05, respectively;

[0038] The collecting device 03 is used to collect the user's characteristic information and send the user's characteristic information to the controller 05;

[0039] The controller 05 is used to match the user's feature information with preset information, identify the user's identity information according to the matching result, and determine whether to lock the gas knob 04 based on the identity information.

[0040] In practical applications, the controller may be disposed inside the gas stove body, the burner and the gas knob may be disposed on the upper surface of the gas stove body; and the igniter may be disposed below the burner.

[0041] The controller can be any control device that can process digital signals and analog signals, including but not limited to single chip microcomputers, microcomputers, and other control devices that can achieve the above functions.

[0042] The burner may include a burner inner ring and a burner outer ring; the burner functions to surround the fire within the burner and prevent the fire from burning outside the burner.

[0043] One end of the above-mentioned gas pipe is connected to the burner, and the other end is connected to the gas source. Specifically, the inner ring of the burner and the outer ring of the burner can be arranged around one end of the gas pipe; at the same time, the gas pipe is also connected to a control valve for controlling whether gas is flowing in the gas pipe (that is, whether the gas is cut off).

[0044] The cross section of the gas stove body can be of any shape, such as rectangular, square, circular or other irregular shapes, etc. The gas pipe and the gas stove body can be fixedly connected or detachably connected.

[0045] The control valve is in a closed state relative to the gas pipeline, which can ensure the daily safety of the integrated stove. The control valve can be specifically an electric control valve, so that the state of the control valve can be adjusted based on the controller.

[0046] The above-mentioned gas knob is connected to the igniter and is used to control the opening and closing of the igniter. The function of the igniter is to ignite the natural gas flowing from the gas pipe to the burner. At the same time, the gas knob is also connected to the control valve, which can control the opening and closing of the control valve, thereby controlling and regulating the flow of gas in the gas pipe; the number of gas knobs can be one or more.

[0047] Specifically, when the gas knob is rotated to open, the gas valve (also known as the control valve mentioned above) can be opened to allow gas to flow into the burner. At the same time, the knob will also trigger the igniter, causing the igniter to generate an electric spark, which will ignite the gas flowing into the burner and produce a flame.

[0048] The above-mentioned collection device can be one or more combinations of a biometric recognition device, a weight sensor, a camera, and a voice collection device.

[0049] The above-mentioned preset information can be one or more combinations of preset pictures, preset weight values, preset photos, preset height values, preset action videos, and preset sound features.

[0050] It should be noted that the above-mentioned preset information can be specifically understood as relevant characteristic information pre-stored in the controller. For example, the preset weight value can be the standard weight value corresponding to an 8-year-old child, and the preset weight value can be the height difference between the standard height corresponding to an 8-year-old child and the height of the gas stove body.

[0051] In actual implementation, the above-mentioned collection device and gas knob are respectively connected to the controller. When the user enters the kitchen and approaches or touches the gas stove, the collection device can collect the user's characteristic information and send it to the controller; the controller can match the user's characteristic information with the corresponding preset information stored in advance to obtain a matching result, and then identify the user's identity information based on the matching result. When it is determined that the user is a child, the controller can lock the gas knob to prevent the child from turning the gas knob to start the fire; when it is determined that the user is not a child, there is no need to lock the gas knob, and the gas knob can operate normally.

[0052] The gas stove provided in the above embodiment includes: a gas stove body, on which is mounted a burner, a data acquisition device, a gas knob, and a controller; the burner is respectively connected to an igniter and a gas pipe, on which a control valve is mounted; the gas knob is respectively connected to the igniter and the control valve; the data acquisition device and the gas knob are respectively connected to the controller; the data acquisition device is configured to collect user characteristic information and transmit the user characteristic information to the controller; the controller is configured to match the user characteristic information with preset information, identify the user's identity information based on the matching result, and determine whether to lock the gas knob based on the identity information. By mounting the data acquisition device on the gas stove body, the utility model can lock the gas knob when a child is detected, thereby effectively avoiding many safety hazards and ensuring the safe use of the gas stove.

[0053] In actual implementation, the collection device 03 can use any one of a biometric recognition device, a weight sensor, a camera, and a voice collection device, but using only one of them is likely to cause identity recognition errors. For example, when only a weight sensor is used, the corresponding stored preset information is the standard weight value corresponding to an 8-year-old child (that is, a preset weight value. People under the age of 8 are usually considered children and pose a greater safety risk in the kitchen). If the weight information recognized by the weight sensor is less than the preset weight value, that is, the user's weight is less than the standard weight value corresponding to an 8-year-old child, the user's identity will be confirmed as a child. However, if the user is actually a fat child or a child with obesity, the user's identity will be confirmed as not a child, resulting in identity recognition errors and the gas knob cannot be locked.

[0054] Therefore, in order to avoid identity recognition errors, the collection device 03 can be implemented by using a combination of biometric recognition equipment, weight sensors, cameras, and voice collection equipment to comprehensively judge the user's identity by collecting multiple feature information.

[0055] In one embodiment, see Figure 2As shown, the collection device 03 can be a combination of a biometric recognition device 031, a weight sensor 032, a camera 033, and a voice collection device 034, that is, the collection device 03 includes the biometric recognition device 031, the weight sensor 032, the camera 033, and the voice collection device 034 at the same time.

[0056] The above-mentioned biometric identification device is usually set on the gas knob. The specific setting position on the gas knob is not limited. For example, it can be set on the upper surface of the gas knob 04 (such as Figure 2 As shown), it can also be set on the side surface or other positions of the gas knob.

[0057] The above-mentioned biological weight sensor can be integrated into the base of the gas stove body or near the base, and detects weight by contact or non-contact method. The type and method of the above-mentioned biological weight sensor are not specifically limited. For example, it can be a carpet-type weight scale, which is laid flat on the ground in front of the gas stove body (such as Figure 2 shown).

[0058] The above-mentioned camera is usually installed in the kitchen. The specific type and location of the camera in the kitchen are not limited. For example, the camera can be installed on the range hood (such as Figure 2 As shown, the range hood can be installed on the upper back side of the gas stove body) or on the wall of the kitchen. The types can be advanced motion recognition cameras, motion detection cameras, or integrated cameras, etc. Among them, the advanced motion recognition camera can analyze whether the operator (user) operates the integrated stove, the motion detection camera can detect whether the user is close to the integrated stove, and the integrated camera can simultaneously detect whether the user is close to the integrated stove and operates the integrated stove.

[0059] The above-mentioned voice collection device can be set on the upper surface of the gas stove body, and the specific type is not limited.

[0060] The above-mentioned collection device can be in an activated state for a long time, collecting the user's characteristic information in real time and sending it to the controller. The controller confirms the user's identity information based on the matching results of the characteristic information and the preset information, and determines the authority corresponding to the gas knob based on the user's identity information, thereby controlling whether the gas knob is locked according to the authority. The authority may include locking authority and non-locking authority. If it is locking authority, the locking mechanism can be activated to control the gas knob to lock. If it is non-locking authority, the gas knob can be controlled to work normally.

[0061] In the specific implementation process, a physically lockable locking device (i.e., the above-mentioned biometric identification device) can be designed on the gas knob. The locking device can collect the user's biometric information and unlock it through the user's biometric information identification or other electronic authentication methods. After the authentication is passed, adults can rotate the knob to use gas. The locking device can specifically be a fingerprint identifier, a palm print identifier, a vein pattern identifier, or an integrated identifier. Among them, the fingerprint identifier can collect the user's fingerprint information, the palm print identifier can collect the user's fingerprint information, the vein pattern identifier can collect the user's vein pattern information, and the integrated identifier can collect any one of fingerprint information, palm print information, and vein pattern information.

[0062] When using the gas stove referred to in this embodiment, the fingerprint of a dedicated user who can operate the gas knob can be entered in advance. The fingerprint information is converted into a template (equivalent to the preset image included in the above preset information) through image processing and stored in the controller. When the fingerprint is input again, the controller will compare the input fingerprint with the template and generate a matching result, and control whether the gas knob is locked based on the matching result. If the matching result indicates that they are different, the gas knob is locked. At this time, the gas knob is closed and no flame is generated inside the burner; if the matching result indicates that they are the same, no operation is performed.

[0063] By installing a biometric recognition device on the gas knob, it can be ensured that only those who have recorded their fingerprint information in advance can turn on a specific gas stove, while people who have not recorded their fingerprint information, such as children, cannot turn it on at will, thereby effectively avoiding many safety hazards and ensuring the safe use of household gas stoves.

[0064] During the specific implementation process, an intelligent weight sensor can also be laid on the ground in front of the gas stove. Its detection range is larger than the standing area in front of the gas stove, ensuring that the operator is above the weight sensor when standing in front of the gas stove. The sensor detects weight through contact or non-contact means, and determines the identity of the user based on the obtained weight value. When the weight of a child is detected, the controller activates the locking mechanism to prevent children from operating the gas knob.

[0065] When using the gas stove referred to in this embodiment, the weight information of the specific user who can operate the gas knob can be input in advance (equivalent to the above-mentioned preset weight value, such as the standard weight value corresponding to an 8-year-old child). The preset information is stored in the controller. When the weight information is input again, the controller will compare the input weight information with the preset weight value, generate a matching result, and control whether the gas knob is locked based on the matching result. If the matching result indicates that the input weight information is less than the preset weight value, the gas knob is locked. At this time, the gas knob is closed and no flame is generated inside the burner; if the matching result indicates that the input weight information is not less than the preset weight value, the operation is not performed.

[0066] During the specific implementation process, a camera can also be installed on the upper part of the gas stove to observe the user standing in front of the gas stove from top to bottom, and based on the visual recognition program, preset photos, preset height values ​​and preset action videos, the controller can determine the user's identity information, where the user's identity information can be divided into children and non-children based on age; it can also be based on more detailed visual recognition settings, and the user identity can be divided into specific members such as parents and children according to family members.

[0067] Specifically, an advanced motion recognition camera can be installed to analyze the operator's behavior. If it detects a child attempting to operate the gas stove, the controller automatically activates the lock mechanism. If an adult operates the stove, the system responds normally. Alternatively, a motion detection camera can be installed. If it detects a child approaching, the controller automatically activates the lock mechanism to prevent the child from operating the gas knob. If an adult approaches, the system responds normally.

[0068] When using the gas stove referred to in this embodiment, preset height information (for example, the height difference between the standard height of an 8-year-old child and the height of the gas stove), facial information of a designated user who can operate the gas knob (equivalent to the above-mentioned preset photo), and preset action videos (for example, the action of attempting to operate the gas stove) can be input in advance. These preset information are stored in the controller. When the currently recognized facial information (that is, the vertical height difference between the user's head and the upper surface of the gas stove body) is input, the controller compares the input facial information with the preset photo and generates a matching result. Based on the matching result, the controller controls whether the gas knob is locked. If the matching result indicates a difference, the gas knob is locked, the gas knob is turned off, and no flame is generated inside the burner. If the matching result indicates a match, no operation is performed.

[0069] When the currently recognized height information (that is, the vertical height difference between the user's head and the upper surface of the gas stove body) is input, the controller will compare the input height information with the preset height value, and generate a matching result, and control whether the gas knob is locked based on the matching result. If the matching result indicates that the height information is less than the preset height value, the gas knob is locked. At this time, the gas knob is closed and no flame is generated inside the burner; if the matching result indicates that the height information is not less than the preset height value, the operation is not performed; when the currently recognized action behavior information is input, the controller will compare the input action behavior information with the preset action video, and generate a matching result, and control whether the gas knob is locked based on the matching result. If the matching result indicates that the similarity meets the preset requirements, the gas knob is locked. At this time, the gas knob is closed and no flame is generated inside the burner; if the matching result indicates that the similarity does not meet the preset requirements, the operation is not performed.

[0070] During the specific implementation process, a voice collection device can also be installed on the upper part of the upper surface of the gas stove body so that the user identity information can be determined based on the collected voice information. When using the gas stove referred to in this embodiment, the voice characteristics of the dedicated user who can operate the gas knob can be input in advance and stored in the controller. When the currently recognized voice information is input, the controller will compare the input voice information with the voice characteristics, generate a matching result, and control whether the gas knob is locked based on the matching result. If the matching result indicates the same, the gas knob is locked. At this time, the gas knob is closed and no flame is generated inside the burner; if the matching result indicates different, the operation is not performed.

[0071] Assuming that a user is actually a child whose weight is greater than the standard weight of an 8-year-old child and whose height is also greater than the standard height of an 8-year-old child, then when using the gas stove referred to in this embodiment, when the weight sensor sends the weight information corresponding to the user to the controller, the controller will not perform any operation. When the camera sends the height information corresponding to the user to the controller, the controller will not perform any operation. When the sound collection device and / or biometric recognition device sends the biometric information and / or sound information corresponding to the user to the controller, the controller may recognize the user's identity information as a child, thereby locking the gas knob.

[0072] It should be noted that other embodiments formed by one or more combinations of biometric recognition devices, weight sensors, cameras, and voice acquisition devices can refer to the above embodiments and will not be described in detail.

[0073] The gas stove provided in the above embodiment, the collection device may include a variety of combinations of biometric recognition devices, weight sensors, cameras, and voice collection devices. By adopting a variety of combinations of biometric recognition devices, weight sensors, cameras, and voice collection devices, a variety of feature information can be collected to comprehensively judge the identity of the user, effectively identify the user's identity, thereby improving the accuracy of child identity recognition.

[0074] Based on the above embodiment, the present invention also provides another gas stove. Figure 3 The structural schematic diagram of another gas stove shown in the figure, based on the above embodiment, the gas stove includes: a thermoelectric potential element 09, which is arranged inside the gas stove body 01 and connected to the controller 05; the thermoelectric potential element 09 is used to collect thermal energy information of the burner 02, and convert the thermal energy information into current information and send it to the controller 05; the controller 05 is used to determine whether to turn off and lock the gas knob 04 based on the current information, a preset current threshold and identity information.

[0075] In actual implementation, when a child appears in the kitchen, the gas stove may be in the off state (no flame in the burner) or in the cooking state (flame in the burner). When the gas stove is in the cooking state, the gas knob is in the working state. If the controller only controls and locks the gas knob, the gas knob is just in a state where it cannot be turned and adjusted, and is not turned off. In this case, there is still a flame in the burner. If a child approaches the gas stove, he or she may touch the flame, posing a safety risk of scalding or burns.

[0076] Therefore, when the controller controls the lock, the thermoelectric potential element can also be used to obtain thermal energy information (for example, when there is a flame in the burner, a large amount of thermal energy is obtained, and the current converted into it is also large).

[0077] When using the gas stove referred to in this embodiment, a current threshold corresponding to the heat energy that can indicate the cooking state can be input in advance and stored in the controller. When the current current information input is recognized, the controller will compare the current information with the preset current threshold and generate a matching result. The controller controls whether the gas knob is closed and locked based on the matching result and identity information. If the matching result indicates that the current information is not less than the current threshold and the identity information is a child, the gas knob is first closed and then locked so that no flame is generated inside the burner; if the matching result indicates that the current information is less than the preset current threshold and the identity information is a child, the gas knob can be directly locked.

[0078] In fact, a camera can also be used to detect whether there is a flame in the burner, but please note that the installation position of the camera needs to be adjusted to a position where it can detect whether there is a flame in the burner.

[0079] The above embodiment solves the problem of children turning on the gas stove by themselves and is unsafe, thereby improving the safety of using the gas stove.

[0080] Based on the above embodiment, the present invention also provides another gas stove. Figure 4 The structural diagram of another gas stove shown is, based on the above embodiment, the gas stove includes an emergency button 10, which is connected to the control valve 08; the emergency button 10 is used to respond to the user's first operation and control the control valve 08 to be urgently closed according to the first operation.

[0081] In fact, in order to protect the emergency button and prevent accidental touching, a protective cover may be provided outside the emergency button.

[0082] The emergency button is a manual emergency shutoff button, specifically a conspicuous and easily accessible manual emergency shutoff button can be provided on the panel of the gas stove. This button directly controls the gas valve (also known as the control valve) through a mechanical connection to ensure that the gas supply can be quickly cut off in an emergency.

[0083] Based on the above embodiment, the present invention also provides another gas stove. Figure 5 The structural diagram of another gas stove shown in the figure, based on the above embodiment, the gas stove also includes a sound prompt device 11, the sound prompt device is provided on the gas stove body 01 and is connected to the controller 05; the sound prompt device 11 is used to prompt the user that the gas knob 04 is locked.

[0084] The above-mentioned sound prompt device can be a device that can make sound, such as a buzzer, a speaker, etc. The setting position of the above-mentioned sound prompt device can be inside the gas stove, and can also be outside.

[0085] Specifically, a sound prompt device can be integrated inside or outside the gas stove. When it detects that a child may be operating in the kitchen or a gas leak occurs, a sound alarm can be issued to remind adults to pay attention to safety. The alarm sound is loud enough to ensure that it can be heard from anywhere in the room.
