Description

Technical Field

[0001] This utility model belongs to the technical field of kitchen utensils, specifically relating to a gas stove with a gas leak protection system. Background Technology

[0002] Gas is commonly used in kitchen appliances such as gas stoves. It burns and produces an open flame to cook food. After a period of use, the internal components of gas stoves will age and are prone to gas leaks. However, once a gas leak occurs, it will have extremely serious consequences. Therefore, it is necessary to strictly monitor the gas concentration in the environment to avoid gas leaks.

[0003] Currently, the most common gas leak monitoring equipment is the gas leak alarm, which is usually purchased separately and installed in the gas usage area. The problem is that when the gas leak is detected, the gas leak monitoring equipment can only emit light and / or sound alarms to the external environment, but the alarm range is very limited. If a gas leak occurs unattended, it cannot be detected in time. In addition, the gas leak monitoring equipment can only issue a warning signal, and there is no direct connection between the gas leak monitoring equipment and the gas pipeline or gas stove. It cannot actively disconnect the gas supply when a gas leak occurs, thus posing certain safety hazards.

[0004] Therefore, further improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to overcome at least one of the shortcomings of the prior art and provide a gas stove with a gas leak protection system, which can detect gas leaks and actively disconnect the gas supply to the gas stove, thereby improving the safety of the gas stove.

[0016] The gas stove also includes a pulse igniter, which is installed on the bottom shell of the stove. The pulse igniter is connected to the control unit by wire or wireless connection.

[0017] When the gas leak detector sends an alarm signal to the control unit, the control unit receives the signal and simultaneously shuts down the pulse igniter.

[0018] The gas leak protection system also includes a power supply component, which is electrically connected to the gas stove, the gas shut-off valve and the control component to provide energy to the gas stove, the gas shut-off valve and the control component respectively. The power supply component includes an AC power supply module that obtains energy from the urban power grid and / or a DC power supply module that obtains energy from a battery.

[0019] Alternatively, the power supply component is electrically connected to the gas stove, gas leak detector, gas shut-off valve, and control component respectively, so as to provide energy to the gas stove, gas leak detector, gas shut-off valve, and control component respectively.

[0020] The gas pipeline is equipped with a gas meter, which is located at the gas inlet of the gas shut-off valve. The gas leakage protection system also includes a manual gas valve, which is installed on the gas pipeline and located between the external gas source and the gas meter, to manually control the gas flow in the gas pipeline.

[0021] The gas leak detector and the control unit transmit signals via Bluetooth, infrared, and radio frequency, and the control unit and the gas shut-off valve transmit signals via Bluetooth, infrared, and radio frequency.

[0022] The gas leak detector is installed on the side and / or bottom surface of the stove base. The gas leak detector includes a detector body and a fixing component.

There are two sliding grooves arranged at intervals along the left and right sides of the back of the detector body. There are two sliding rails arranged opposite to each other on the left and right sides of the fixed component. The sliding grooves and sliding rails slide and cooperate with each other.

[0024] The fixing component is provided with a limiting protrusion for fixing the component to be installed on the detector body. The limiting protrusion is located on the top surface of the slide rail and near the front side of the fixing component.

[0027] The beneficial effects of this utility model are as follows:

[0028] This utility model, through the adoption of the above technical solution, provides a gas stove with a gas leak protection system. When the gas leak detector detects that the gas concentration around the gas stove is higher than its set value, the gas leak detector sends an alarm signal to the control component and actively closes the gas shut-off valve to cut off the gas supply to the gas stove. The gas leak protection system can promptly cut off the gas supply. When the gas concentration is lower than the set value of the gas leak detector, the gas shut-off valve needs to be manually reset to reconnect the gas supply to the gas stove, thus improving the safety of the gas stove.

[0029] The gas stove with gas leak protection system described above also includes an alarm component. After receiving a signal from the control component, the alarm component sends out light and sound alarms to the external environment. When a gas leak occurs, people within the alarm range can promptly detect and handle the gas leak, further improving the safety of the gas stove.

[0030] The above technical solution includes a remote notification component for gas stoves with a gas leak protection system. After receiving information from the gas shut-off valve, the remote notification component notifies the user. When a gas leak occurs unattended, personnel outside the alarm range can still promptly detect the gas leak, further improving the safety of the gas stove. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0039] See Figure 1-7 This gas stove with a gas leak protection system includes a stove base 1, which is connected to a gas pipeline via a connector, allowing an external gas source to supply gas to the stove. The gas leak protection system includes a gas leak detector 2, a gas shut-off valve, and a control component. The gas leak detector 2 is preferably a semiconductor detector, which is detachably installed on the stove base 1, enabling it to detect the gas concentration around the stove in a timely manner. The gas shut-off valve is preferably an electromagnetic valve, which is located on the gas pipeline at the gas inlet end of the stove base 1. When the gas shut-off valve is de-energized, it is in a connected state, allowing gas to flow to the stove. When the gas shut-off valve is energized, it is in a closed state, preventing gas from flowing to the stove. This allows the gas shut-off valve to automatically control the flow of gas into the stove base 1. The control component is preferably an infrared remote control or a Bluetooth remote control, which is installed in an indoor location and transmits signals to the gas leak detector 2 and the gas shut-off valve via infrared, Bluetooth, and radio frequency, respectively. This allows the control component to receive alarm signals from the gas leak detector 2 and send control signals to the gas shut-off valve.

[0040] When the gas leak detector 2 detects that the gas concentration around the gas stove is higher than its set value, the gas leak detector 2 sends an alarm signal to the control unit and actively closes the gas shut-off valve to cut off the gas supply to the gas stove. The gas leak protection system can promptly cut off the gas supply. When the gas leak detector 2 detects that the gas concentration around the gas stove is lower than its set value, the gas shut-off valve needs to be manually reset to reconnect the gas supply to the gas stove, thus improving the safety of the gas stove.

[0041] Furthermore, the gas leak protection system also includes an alarm component. Specifically, in this embodiment, the alarm component is preferably a household gas alarm, which is installed in the gas usage area and has audible and visual alarm functions. The alarm component and the control component are electrically connected by wires or other means. When the gas leak detector 2 detects that the gas concentration around the gas stove is greater than its set value and sends an alarm signal to the control component, the alarm component receives the signal from the control component and sends out a visual and audible alarm to the external environment, enabling people within the alarm range to promptly detect and handle the gas leak, further improving the safety of the gas stove. This is understood by those skilled in the art.

[0042] Furthermore, the gas leak protection system also includes a remote notification component, which is connected to the gas shut-off valve via a network. Specifically, in this embodiment, the remote notification component includes a network router, a smart cloud platform, and a user mobile device. The network router and the user mobile device are connected to the smart cloud platform via the Internet, and the gas shut-off valve is connected to the network router via a wireless local area network. When the gas leak detector 2 detects that the gas concentration around the gas stove is greater than its set value and sends an alarm signal to the control component, the control component actively closes the gas shut-off valve. After receiving the information from the gas shut-off valve, the remote notification component notifies the user, so that people outside the alarm range can still receive relevant information about the gas shut-off valve in a timely manner and discover a gas leak, further improving the safety of using the gas stove. This is something that those skilled in the art can understand.

[0043] Furthermore, the gas stove also includes a pulse igniter. Specifically, in this embodiment, the pulse igniter is installed inside the bottom shell 1 of the stove, and its ignition end extends into the combustion end of the gas stove to ignite the burner. The pulse igniter and the control component are connected by a wire to achieve a wired connection between the two, which is used by the control component to control the pulse igniter. When the gas leak detector 2 sends an alarm signal to the control component, the control component receives the signal and cuts off the power supply to the pulse igniter to shut it off, thereby further improving the safety of the gas stove. This is understandable to those skilled in the art.

[0044] Furthermore, the gas leak protection system also includes a power supply component. Specifically, in this embodiment, the power supply component includes an AC power supply module that obtains energy from the city power grid and a DC power supply module that obtains energy from a battery. The AC power supply module is external to the gas leak protection system and is electrically connected to the gas shut-off valve via wires or other means, enabling the gas shut-off valve to obtain stable and long-lasting energy. The DC power supply module is built into the gas leak protection system, that is, both the gas stove and the control component are equipped with DC power supply modules. The power supply component located on the gas stove supplies power to the pulse igniter and gas leak detector 2 inside the gas stove, and the power supply component located on the control component supplies power to the control component. This allows the gas stove and control component to obtain energy without wired connection, expanding the placement range of the gas stove and control component, making it easier for users to change the placement of the gas stove and to access the control component. This can improve the user experience of the gas leak protection system to a certain extent, as those skilled in the art can understand.

[0045] Alternatively, the gas stove, gas leak detector 2, and control unit can all be equipped with DC power supply modules. The power supply module on the gas stove supplies power to the pulse igniter inside the gas stove, the power supply module inside the gas leak detector 2 supplies power to the gas leak detector 2, and the power supply module inside the control unit supplies power to the control unit. This allows the gas stove, gas leak detector 2, and control unit to obtain energy without wired connection, thus expanding the placement range of the gas stove, gas leak detector 2, and control unit. This makes it easier for users to change the placement of the gas stove and the detection position of the gas leak detector 2, and to easily access and place the control unit. To a certain extent, this can improve the user experience of the gas leak protection system, as will be understood by those skilled in the art.

[0046] Furthermore, a gas meter is installed on the gas pipeline, located at the gas inlet end of the gas shut-off valve. In this embodiment, both the gas meter and the gas shut-off valve are installed on the main gas pipeline, enabling the gas shut-off valve to control the on / off of the entire gas pipeline and prevent gas leakage from the secondary pipeline, further improving the safety of the gas stove. The gas leakage protection system also includes a manual gas valve. In this embodiment, the manual gas valve is preferably a ball valve, which is installed on the gas pipeline and located between the external gas source and the gas meter. The manual gas valve allows manual control of the gas flow in the entire gas pipeline, facilitating maintenance of the gas pipeline and the gas stove, as understood by those skilled in the art.

[0047] Furthermore, the gas leak detector 2 includes a detector body 21 and a fixing component 22. Specifically, in this embodiment, the gas leak detector (2) is disposed on the bottom surface of the stove bottom shell (1). A sliding mounting structure is provided between the detector body 21 and the fixing component 22. The fixing component 22 can be mounted and dismounted on the detector body 21 through the sliding mounting structure. An installation structure is provided between the fixing component 22 and the stove bottom shell 1. The fixing component 22 is fixedly mounted on the stove bottom shell 1 through the installation structure. Through the above technical solution, the detector body 21 is installed on the stove bottom shell 1 through the fixing component 22, thereby realizing that the gas leak detector 2 is disposed on the stove bottom shell 1. This is understood by those skilled in the art.

[0048] Furthermore, in this embodiment, the sliding assembly / disassembly structure includes a slide groove 210 and a slide rail 220. Specifically, the slide groove 210 is disposed on the detector body 21, preferably two of which are spaced apart along the left and right sides of the back of the detector body 21. The slide rail 220 is disposed on the fixing component 22, preferably two of which are disposed opposite to each other on the left and right sides of the fixing component 22. When the slide rail 220 extends into the slide groove 210 and slides from the front end to the rear end of the slide groove 210, the fixing component 22 is installed on the detector body 21. When the slide rail 220 slides from the rear end to the front end of the slide groove 210 and comes out of the slide groove 210, the fixing component 22 is disassembled from the detector body 21. Through the above technical solution, the fixing component 22 is mounted and disassembled on the detector body 21, which can be understood by those skilled in the art.

[0049] Furthermore, in this embodiment, the fixing component 22 is provided with a limiting protrusion 221. Specifically, the limiting protrusion 221 is provided on the top surface of the slide rail 220 and extends upward and is close to the front side of the fixing component 22. When the fixing component 22 is installed on the detector body 21, the front end of the slide groove 210 abuts against the limiting protrusion 221. Through the above technical solution, the fixing component 22 is limited to be installed on the detector body 21, which can be understood by those skilled in the art.

[0050] Furthermore, in this embodiment, a locking structure is provided between the detector body 21 and the fixing component 22. Specifically, the locking structure includes a locking protrusion 211 and a locking recess 222. The locking protrusion 211 is disposed on the detector body 21, preferably two of which are respectively disposed on the top surfaces of the two slide grooves 210. The locking recess 222 is disposed on the slide rail 220, preferably two of which are respectively disposed on the top surfaces of the two slide rails 220. When the slide rail 220 extends into the slide groove 210, the locking protrusion 211 and the locking recess 222 engage with each other, so that the fixing component 22 is locked on the detector body 21. This is understood by those skilled in the art.

[0051] Furthermore, in this embodiment, an installation structure is provided between the fixing component 22 and the stove base shell 1. Specifically, the installation structure includes mounting screw holes 101, mounting through holes 223, and fastening components 23. Preferably, there are two mounting screw holes 101, which are located on the bottom surface of the stove base shell 1. The number of mounting through holes 223 corresponds to the number of mounting screw holes 101, which are also located through the fixing component 22. The fastening component 23 is preferably a screw. When the fixing component 22 is placed on the bottom surface of the stove base shell 1, the fastening component 23 passes through the mounting through holes 223 and engages with the mounting screw holes 101, so that the fixing component 22 is fixed on the stove base shell 1. This is understood by those skilled in the art.
