Embodiment 1

[0037] Such as image 3 As shown, the environment detection component 7 includes a human body activity sensor 6 and a noise detector, and the high-efficiency operation of the fresh air fan can be realized through the cooperation of the two. In addition, the fresh air machine includes a heating assembly, a temperature detector and a human body activity sensor 6 to provide a warm and comfortable cooking environment for users.

[0038] In actual operation, when the human body activity sensor 6 is triggered, the noise detector starts with a delay and obtains the noise point parameters, and the controller is provided with a parameter threshold corresponding to the noise detector, and the controller There are pre-stored the body noise parameters of the fresh air blower when they are in the low-speed state, medium-speed state and high-speed state respectively. The noise point parameters will form real-time noise for the controller to control the operation state of the exhaust fan 4 a...

Embodiment 2

[0058] Compared with the first embodiment, this embodiment provides another fresh air fan of the environment detection component 7 .

[0059] Such as Figure 4 As shown, the environment detection component 7 is a dust detector and a humidity detector, and the high-efficiency operation of the fresh air fan can be realized through the cooperation of the two. In addition, the fresh air machine includes a heating assembly, a temperature detector and a human body activity sensor 6 to provide a warm and comfortable cooking environment for users.

[0060] In actual operation, the structure and control method of the heating assembly are the same as those in Embodiment 1, and will not be repeated here.

[0061] In the implementation operation, the controller is provided with parameter thresholds corresponding to the dust detector and the humidity detector respectively, and thus forms the shutdown maintenance interval, the low speed maintenance interval, the medium speed maintenance i...

Embodiment 3

[0071] Compared with Embodiment 1 or Embodiment 2, this embodiment provides another new fan structure.

[0072] Such as Figure 5 As shown, the air outlet of the air inlet duct 3 is provided with a heating assembly. When the human body motion sensor 6 is triggered, the airflow in the air inlet duct 3 flows through the heating assembly in the operating state to form hot air. The fresh air blower includes a heating assembly, a temperature detector and a human body activity sensor 6. The controller is provided with a trigger temperature B, and the temperature detector senses and obtains the real-time temperature C of the first indoor space. Take the kitchen environment as an example, when using:

[0073] When the human body activity sensor 6 is triggered by a moving object and C

Abstract

The invention relates to a fresh air ventilator and a control method thereof. Existing fresh air ventilators cannot automatically adjust the operating state as needed. The fresh air ventilator comprises a casing and an exhaust air duct; the fresh air ventilator comprises an environment detecting component; and a human body activity sensor and the environment detecting component sense the real-timehuman body activity state and environmental parameters, so that the exhaust fan can be switched between a shutdown state and operating states with different powers. The environmental detecting component is additionally arranged on an existing fresh air ventilator, air with steam or solid particles in a first inner space is discharged through the exhaust air duct, the operating states of the freshair ventilator can be adjusted according to actual needs, steam and solid particles in the first indoor space can be discharged out by the fresh air ventilator in time, the cleanliness of air in thefirst indoor space is ensured, the health of a user is ensured, depreciation and abrasion of the fresh air ventilator can be reduced by reducing the operation load and duration of the exhaust fan, andthe service life of the fresh air ventilator is prolonged.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a fresh air fan and a control method thereof. Background technique [0002] The existing fresh air blower plays the role of updating the indoor air. Due to the relatively closed indoor environment, the indoor air with solid particles or water vapor cannot be diffused in time, which is likely to cause harm to the health of indoor personnel. The existing new fan includes an air inlet duct and an exhaust air duct. An air inlet fan is arranged in the air inlet duct, and an exhaust fan is arranged in the exhaust air duct. During operation, the air inlet fan and the exhaust fan are synchronized. Operation, removes room air by directing the airflow to circulate. However, most of the existing fresh air fans are in manual mode, which cannot be switched according to actual needs, which not only affects the efficiency of indoor air discharge, but also tends to waste electric energy due...
