Description

Technical Field

[0001] The invention belongs to the technical field of kitchen and bathroom equipment control, and in particular relates to an air supply system of an intelligent linkage socket of a range hood and a control method thereof. Background Art

[0002] Passive ultra-low energy consumption buildings (hereinafter referred to as passive houses) refer to buildings that adapt to climate characteristics and natural conditions, provide a comfortable indoor environment through enclosure structures with higher thermal insulation and airtightness, adopt fresh air heat recovery technology, and utilize renewable energy.

[0003] According to the strict airtightness requirements of passive houses, the doors and windows of passive houses are closed in winter when indoor heating is used and in summer when cooling is used. At this time, when the range hood in the kitchen of the passive house is turned on, the fumes are difficult to be discharged due to the lack of an air inlet device. At the same time, the negative pressure in the kitchen is increased, and the foul air in the drainage pipes, floor drains and other places flows back into the room, causing odor to pollute the indoor environment.

[0004] To solve this indoor negative pressure phenomenon, the current common practice is to control the air intake valve through a linkage device to supplement the positive pressure in the kitchen. When the range hood is working, the air intake valve is opened in time to allow fresh air from the outside to enter the room. When the range hood is not working, the air intake valve is closed to prevent outdoor cold / hot air from entering the room. However, due to different brands and powers of range hoods, when the range hood is turned on to the maximum power, a single air intake valve cannot meet the air intake requirements, and the kitchen will still form too much negative pressure, resulting in poor extraction of oil smoke and odors from drainage pipes and floor drains flowing back into the kitchen.

Example

[0020] like Figure 3 As shown, this embodiment provides an air supply system for a range hood intelligent linkage socket, including: an intelligent linkage socket 6, a range hood 7, an exhaust duct 8, a one-way exhaust valve 9, a water retaining cover 10, a water retaining air filter cover 11, an air supply valve 12, an air supply fan 13, an air intake duct 14, a wind tunnel plate 15, a building cement wall 16, and a gas furnace 17. Example

[0021] This embodiment specifically relates to a control method for an air supply system of a range hood intelligent linkage socket, comprising the following steps: Step 1: Turn off the main power supply of the kitchen in the distribution box, correctly connect the AC220V power supply, air supply valve, and air supply fan to the smart linkage socket 6 according to the terminal markings on the back of the smart linkage socket 6, and then turn on the main power supply of the kitchen.

[0022] Step 2: The first 60 seconds before powering on is the learning mode, to learn the range hood 7 to obtain the power of each gear. Plug the range hood 7 into the socket and turn it on, switch from low gear, medium gear, and high gear in turn, and ensure that each gear stays for about 5 seconds. The power acquisition submodule in the intelligent linkage socket 6 collects the power of each gear and passes it to the MCU module and saves its power value. After the MCU submodule monitors that the power value of a certain gear stays for more than 20 seconds, the socket exits the learning mode and enters the normal working mode. Through learning and adaptation, the MCU submodule in the socket can obtain the maximum power value of the current range hood by sorting and comparing (hereinafter replaced by M).

[0023] Step 3: In normal mode, the intelligent linkage socket 6 monitors the working state of the range hood 7 in real time and controls the opening and closing of the air supply valve 12 and the wind speed of the air supply fan 13. When the range hood 7 is turned on and adjusted to a low gear, the power acquisition submodule of the intelligent linkage socket 6 collects the power of the range hood 7 as N1, and transmits the power N1 to the MCU module through the serial bus; after the MCU module determines that N1 is greater than the threshold power of 20W, it lights up the status indicator on the surface of the socket through the LED submodule; opens the air supply valve through the relay module; and adjusts the voltage V1 of the air supply fan 13, i.e., the wind speed of the air supply fan, through the zero-crossing detection module and the AC voltage regulation module. The voltage V1 of the air supply fan 13 is N1 / M*220.

[0024] At this time, the fan of the range hood 7 in the kitchen discharges the fumes of the gas stove and the air above to the outside through the exhaust duct 7; the intelligent linkage socket 6 controls the air supply fan 13 to filter the outdoor air through the water-blocking air filter cover 11 and then enter the room through the wind tunnel plate 15, forming a gas circulation with the exhaust system, so that the pressure in the kitchen is maintained at a constant value.

[0025] Step 4: When the gear of the range hood 7 is adjusted to the middle gear under normal working conditions, the MCU module of the socket detects that the power of the range hood 7 increases to N2 through the power acquisition module, and immediately adjusts the voltage of the air supply fan 13 to V2 to increase the wind speed, so that V2 is N2 / M*220. In this way, the exhaust volume is increased after the gear of the range hood 7 is increased, and the intelligent linkage socket 6 controls the air supply fan 13 to increase the air intake volume, so that the indoor air pressure reaches a dynamic balance again.

[0026] Step 5: When the range hood 7 is adjusted to a high gear under normal working conditions, the intelligent linkage socket 6 monitors that the power of the range hood 7 increases to N3, and adjusts the voltage V3 of the air supply fan 13 to make the current V3 N3 / M*220. In this way, the range hood 7 reaches the maximum gear to maximize the exhaust volume, and the intelligent linkage socket 6 regulates the air supply fan 13 to run at the maximum speed, and the indoor air pressure reaches a dynamic balance again.

[0027] Step 6: When the range hood 7 is turned off under normal working conditions, the intelligent linkage socket 6 monitors the range hood 7 power N4 and slowly decreases, and then adjusts the supply air fan 13 voltage V4 to slowly decrease. When N4 drops below the threshold power of 20W, the intelligent linkage socket 6 adjusts the supply air fan 13 voltage to 0, and at the same time closes the supply air valve 12 through the relay module, and turns off the status indicator on the surface of the intelligent linkage socket 6 through the LED module.

[0028] Step 7: The intelligent linkage socket 6 enters the standby mode, constantly monitors the power of the range hood 7 and prepares to repeat the logical actions of step 3 to step 6.

[0029] The present embodiment provides a control method for an intelligent linkage socket of a range hood, wherein the intelligent linkage socket 6 monitors the working status of the range hood 7 in real time, links the air supply valve 12 and the air supply fan 13, and adjusts the voltage of the air supply fan 13 in real time according to the power of the range hood 7, thereby adjusting the wind speed of the air supply fan 13, so that the exhaust volume and the air supply volume reach a dynamic balance, ensuring that the indoor negative pressure is maintained within a certain range, thereby ensuring a comfortable cooking environment and strict air tightness.

Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
