Description

Technical Field

[0001] The utility model relates to the technical field, and in particular to a range hood linkage air supply and exhaust device for a three-constant system. Background Art

[0002] Different from traditional air conditioners (such as wall-mounted units, multi-split central air conditioners, fan coils, etc.) that use convection as the main heat exchange method, the radiation air conditioning system mainly uses heat radiation to adjust the temperature. It has many advantages such as no wind feeling, high comfort, gentle heat exchange, and uniform indoor temperature. However, there is a risk of indoor water vapor condensation when it is used for cooling, which needs to be solved with a dehumidification fresh air system.

[0003] The dehumidified fresh air assumes the function of fresh air for the indoor dehumidifier. In order to make the ventilation efficiency higher, multiple exhaust fans will be installed indoors to optimize the airflow organization. In order to prevent high-humidity outdoor air from entering the house, a slight positive pressure will be maintained indoors. Therefore, the theoretical design exhaust volume is less than the air supply volume of the dehumidified fresh air fan.

[0004] The air volume of range hoods on the market is 1000-1300m 3 / h, the air volume of the system dehumidification fresh air fan is selected according to 30m 3 / h·1㎡ configuration, the dehumidification fresh air machine selected for the 300㎡ panel apartment is 1000m 3 / h. After the range hood is turned on, negative pressure will appear in the kitchen and nearby areas, causing high-humidity outdoor air to enter the room, increasing the risk of condensation on the radiation panel.

[0005] The existing solution is to make vents on the exterior wall near the range hood, such as the kitchen. When the range hood is turned on, air is supplied from the vents to reduce the negative pressure in the room. This solution has the following problems: 1. The air supply from the vents is insufficient. 2. When the range hood is not turned on, it is easy to cause indoor air leakage and condensation. Utility Model Content

A range hood 11 is installed, and a hood duct 12 is fixedly connected to the interior of the range hood 11, and the hood duct 12 extends to the outside of the wall 1. A linkage signal line 13 is arranged inside the range hood 11, and the other end of the linkage signal line 13 away from the range hood 11 is electrically connected to the motor 4. The fan blades 5 are driven by the motor 4 to rotate, and the indoor air passes through the exhaust port 9 and the exhaust check valve 10 and then passes through the second air duct 6 and finally is discharged from the second air supply port 14. The check function of the air supply check valve 8 takes effect, and the first air supply port 7 is closed to play an exhaust role, so as to avoid solving the problem of air leakage when the range hood 11 is not turned on. When the range hood 11 is running, the linkage signal line 13 triggers the motor 4 to drive the fan blades 5 to reverse, the exhaust check valve 10 is closed, and the air supply check valve 8 is opened, so that the external air is sucked into the room for air supply, so as to realize the equipment of the air supply function, solve the problem of insufficient air supply, and start the air supply function of the linkage range hood 11.

[0024] To sum up: when the range hood 11 is not running, the motor 4 drives the fan blades 5 to rotate, so that the combination forms an exhaust device, enters the exhaust check valve 10 through the exhaust port 9, and is then discharged to the outside through the second air supply port 14. At the same time, the non-return function of the air supply check valve 8 takes effect, closing the first air supply port 7 to play an exhaust role. When the range hood 11 is running, the motor 4 is triggered by the linkage signal line 13 to drive the fan blades 5 to reverse, the exhaust check valve 10 is closed, and the first air supply port 7 is opened to supply air to the room. The motor 4 is used to drive the fan blades 5 as an air supply device, and the linkage signal line 13 is triggered by the range hood 11 to link the motor 4 to drive the fan blades 5 to flip and operate to achieve the purpose of air supply.
