Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of Internet of Things, in particular to a range hood and system for a smart kitchen system. Background Art
[0002] When the carbon monoxide in the kitchen exceeds the standard, it needs to be discharged outdoors in time to reduce the concentration of carbon monoxide, otherwise it will cause suffocation and death. However, the leakage of carbon monoxide is usually a slow process. The carbon monoxide produced by the incomplete combustion of carbon substances is colorless, odorless, and non-irritating. It is difficult to be discovered by people indoors. By the time it is discovered, the people indoors may have been poisoned by inhaling carbon monoxide and unable to escape or turn off the valves of the gas equipment.
[0003] Therefore, there is a conception that the data of excessive carbon monoxide detected by the detection equipment is uploaded to the cloud or wirelessly sent to the remote control terminal through the wireless communication module. The cloud or remote control terminal can then perform remote control based on the received excessive data and realize intelligent control based on the carbon monoxide concentration. In addition to turning off the gas meter and gas equipment, the kitchen range hood can also be turned on. In this way, the danger caused by excessive carbon monoxide can be avoided in time, and the risks caused by human operation can also be reduced.
[0004] The realization of the above concept requires that the range hood has the function of remote control. If the range hood can only be turned on or off locally but cannot be remotely controlled, then the above concept of realizing intelligent control based on carbon monoxide will not be realized. Utility Model Content
[0005] The purpose of the invention of the utility model is to improve the range hood of a household kitchen in view of the above-mentioned concept, so that the range hood of a household kitchen can receive a control signal from the cloud or a remote control terminal, and when the carbon monoxide exceeds the standard, turn on the fan of the range hood to speed up the gas flow and reduce the concentration of carbon monoxide. Therefore, a range hood and system for a smart kitchen system are proposed.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A range hood for a smart kitchen system comprises a range hood body, a range hood controller and a communication module. The range hood controller and the communication module are mounted on the range hood body. The communication module is communicatively connected to the range hood controller. The communication module is used to output a wireless control signal received from the outside to the range hood controller. The range hood controller controls the range hood to be turned on or off according to the wireless control signal.
[0008] As a preferred solution, the communication module is one of the 2G, 3G, 4G or 5G communication modes.
[0009] As a preferred solution, the input end of the range hood controller is connected to the communication module, and the output end of the range hood controller is connected to the switch of the fan in the range hood.
[0010] As a preferred solution, the communication module adopts an NB-loT communication module.
[0011] Based on the same concept, a range hood system for a smart kitchen system is also proposed, which uses any of the range hoods for a smart kitchen system described above, and also includes an alarm and a control background.
[0012] The alarm is used to collect carbon monoxide concentration data and transmit the control signal when the carbon monoxide concentration exceeds the standard to the control background;
[0013] The communication module obtains the control signal from the control background, and the communication module is used to send the control signal to the range hood controller. The range hood controller receives the control signal and turns on the switch of the fan in the range hood.
[0014] As a preferred solution, the alarm includes an alarm communication module and an alarm controller.
[0015] The alarm controller sends the control signal after the collected carbon monoxide concentration exceeds the standard to the control background through the alarm communication module.
[0016] As a preferred solution, the alarm controller adopts a CO / CH4 composite concentration detection alarm of model JTM-AEC2368N.
[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0018] Based on the existing kitchen range hood, a communication module is added, so that the kitchen range hood can receive remote control signals through the communication module and can cooperate with remote control instructions to turn on the fan. When the carbon monoxide in the kitchen exceeds the standard, the improved range hood for the smart kitchen system can receive the remote control signal and automatically turn on the fan according to the remote control signal, speeding up the gas flow and reducing the concentration of carbon monoxide to avoid the expansion of harm.

[0021] Figure 3 It is a range hood system for a smart kitchen system in Example 2. DETAILED DESCRIPTION
[0022] The utility model is described in detail below in conjunction with the accompanying drawings.
[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0024] Example 1
[0025] A range hood for a smart kitchen system, such as Figure 1 As shown, it includes a range hood body, a range hood controller and a communication module. The range hood controller and the communication module are installed on the range hood body. The communication module is communicatively connected to the range hood controller. The communication module is used to output a wireless control signal received from the outside to the range hood controller; the range hood controller controls the range hood to be turned on or off according to the wireless control signal.
[0026] For example, the control background sends a high level "1" wirelessly, and the high level "1" means that the fan of the range hood needs to be turned on. The communication module on the range hood receives the high level "1" signal wirelessly, and then transmits the high level "1" signal to the MCU on the range hood controller. The MCU outputs the high level "1" to the peripheral circuit through the I / O pin, and controls the on and off of the relay on the power board through the peripheral amplifier circuit, thereby controlling the start and stop of the fan. When the fan is started, the rotating impeller drives the air to flow, forming an airflow, thereby drawing the air in the kitchen to the outside.
[0027] Specifically, the input end of the range hood controller is connected to the communication module, and the output end of the range hood controller is connected to the switch of the fan. The range hood controller and the communication module are installed on the panel of the range hood body to facilitate receiving wireless signals.
[0028] As a preferred embodiment, the communication module is one of 2G, 3G, 4G or 5G communication modes. As a specific embodiment, the communication module is an NB-IoT communication module, preferably a Quectel BC26 module of Quectel Communications. The functional block diagram of the Quectel BC26 module is as follows: Figure 2 As shown in the figure, the Quectel BC26 module adopts LCC SMD package and has a compact size of 17.7 mm × 15.8 mm × 2.0 mm, which can meet the needs of terminal equipment for small-size module products to the greatest extent. The module provides a variety of external interfaces (UART, ADC, and USIM, etc.). As a preferred solution, in this embodiment, the Quectel BC26 module communicates with the range hood controller via UART.
[0029] As the preferred solution, the range hood controller uses a single-chip microcomputer to realize its functions, and the single-chip microcomputer selected is HC32F005C6PA from HuaDa Semiconductor.
[0030] Example 2
[0031] like Figure 2 The figure shows a range hood system for a smart kitchen system, including the range hood for a smart kitchen system in Example 1, and also including an alarm and a control background. The alarm is used to collect carbon monoxide concentration data, and transmit the alarm signal (also understood as a control signal, such as a high level "1") data after the carbon monoxide concentration exceeds the standard to the control background; after the communication module obtains the control signal from the control background, the communication module is used to send the control signal to the range hood controller, and the range hood controller receives the control signal and turns on the fan of the range hood.
[0032] Preferably, the alarm includes an alarm controller, and the alarm controller sends the collected carbon monoxide concentration data to the control background through the communication module. That is, the alarm communication module is used to send alarm signals and excess data, and the communication module on the range hood is used to receive control signals. The alarm signal can be a high-level signal "1" to turn on the fan of the range hood. Therefore, the control background only needs to perform simple forwarding without converting the data. The control background acts as a transfer station (or relay device) to directly send out the high-level signal "1" to turn on the fan of the range hood. The communication module in the range hood receives the high-level signal "1" wirelessly, and then transmits the high-level signal "1" to the range hood controller. The range hood controller outputs a high-level "1" to the fan switch electrically connected to it, controls the fan to turn on, and the fan rotates. The air in the kitchen is drawn out to the outside, and the carbon monoxide concentration in the room is reduced.
[0033] The alarm device adopts a CO / CH4 composite concentration detection alarm device of model JTM-AEC2368N with NB wireless communication.
[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
