Description

Backstop air door linkage device

This creation is related to a backstop damper linkage device, which belongs to the field of fan exhaust technology. It has the effect of linking and controlling the fan and the electric backstop damper to open or close synchronously, which can effectively reduce wind loss and prevent human negligence from affecting the opening and closing of the damper.

Fan is a mechanical device that converts mechanical kinetic energy into air kinetic energy. It is widely used in buildings as air conditioning systems, ventilation systems or smoke exhaust systems. Take the must-have range hood in the kitchen as an example:

Range hood is a kind of modern kitchen equipment, which is mainly used to remove the cooking fume generated in the indoor cooking process, but also can be used to remove water vapor and odor. Oil fume is the gas and aerosol that edible oil vaporizes and decomposes at high temperature. Modern chemistry believes that it contains many carcinogens. The installation of a range hood is one of the functions to avoid inhaling carcinogens. Whether it is lard, salad oil or peanut oil, the mutagens in the oil fume produced contain polycyclic aromatic A, polycyclic aromatic amines, and nitro-polycyclic aromatic A substances. Studies have confirmed that oil fume is carcinogenic Damage to human DNA. The mutagenicity of oil fume also increases with the increase in temperature and heating time. Animal experiments have found that whether it is animal or vegetable edible oil, once the burning temperature reaches 250 degrees Celsius, it can cause changes in animal cells. The temperature rises to 300 degrees Celsius, and the cell changes even more. As the temperature increases, the concentration of carcinogens in oil fume also increases. The range hood is installed directly above the stove or other heating elements. The main body is an inverted funnel-shaped or rectangular air hopper, and the upper part is exhausted by a motor. Most of the extracted oil and gas are discharged to the outdoors through the exhaust pipe. However, most of the gates are not provided between the motor and the exhaust pipe. When the range hood stops operating, strong outdoor wind, lampblack exhaust gas, peculiar smell, dust, insects or foreign objects drifting with the air will enter the range hood through the exhaust pipe Inside, it enters the indoor kitchen through the suction port of the range hood facing down, which seriously affects the quality of home life.

Conventional technologies mostly use wind, electric, or manual opening methods, which can cause wind damage or easily forget to open or close, resulting in failure to perform functions or reduce performance. Moreover, the relay smoke control device of the range hood of my country Patent Publication No. M517352 (refer to the patent publication data on February 11, 2016) mainly includes one or more relay exhaust fans and a control circuit. Among them, the control circuit is connected to the range hood and the relay exhaust fan, which is provided with a power detection unit and a forced start button, and the relay exhaust fans are arranged at appropriate positions of the exhaust pipe of the range hood. When the range hood is turned on, the power detection unit of the control circuit detects the power of the range hood. When the power is greater than the set value, through the judgment of the control circuit, start one or more relay exhaust fans, or by The forced start button is used to forcibly turn on the relay exhaust fans, so that the fume is discharged in a relay manner to improve the smoke exhaust effect. China Patent Announcement No. M333531 can be linked to the enhanced exhaust device of the range hood (refer to the patent announcement data on June 1, 2008), including a range hood and an outdoor exhaust fan installed outdoors, between the two bodies Connected by an exhaust pipe, a control switch is provided on the range hood and the outdoor air extractor respectively, and a linkage socket is provided on the outdoor air extractor for plugging in a range hood power cord of the range hood. When the control switch of the outdoor air extractor is switched to ON, the outdoor air extractor is activated, while the exhaust fan of the range hood does not operate, so as to be suitable for cooking food for a long time and with less oily smoke. When it is switched to OFF, the outdoor air is exhausted. The hood and the range hood are in a linked standby state. In the linked standby state, turning on the control switch of the range hood can start the range hood and the exhaust fan of the outdoor air extractor at the same time to apply to a large amount of cooking fume. However, although the aforementioned previous cases can effectively reduce wind damage and prevent human negligence from affecting the opening and closing of the damper, they are lacking because of their complicated installations or inconvenient use. This deficiency is an urgent problem in the industry.

In view of the shortcomings of the aforementioned conventional techniques, after continuous research and improvement, the creator of this creation has finally succeeded in the research and creation of this creation and made it public, which can effectively reduce wind damage and prevent human negligence from affecting the opening and closing of the air door.

The reason is that the main purpose of this creation is to provide a "backstop damper linkage device", which mainly includes a body with a power input socket to electrically connect to an external power source, and a power output socket to electrically connect the body Connect the fan power source. The main body is provided with a damper connection seat to electrically connect the electric backstop damper on the fan exhaust pipe. The main body also includes a current sensing device to electrically connect the aforementioned power input seat, power output seat and damper connection When the fan is turned on, the current sensing device senses a current signal, and controls the electric backstop damper on the exhaust pipe of the fan to open, so that the exhaust is smooth. When the fan is turned off, the current sensing device senses the current signal and controls the fan exhaust. The electric backstop damper on the air duct is closed to close the exhaust duct. It has the function of linking the fan and the electric backstop damper to open or close synchronously, which can effectively reduce wind loss and avoid human negligence to affect the opening and closing of the damper.

The aforementioned fan in this creation is a range hood.

The aforementioned current sensing device in this creation is a current sensing switch with no actual contact point, which has the effects of fast switching on and off and long service life.

In order to achieve the above-mentioned technical means of the creation, here is an example, combined with the schematic description as follows, your review committee can obtain a better understanding of the structure, characteristics and effects of the creation.
