Problems solved by technology

It can be seen that the fresh air fan of this fan device is used to accelerate the blowing of oil fume to the smoke exhaust pipe. Although it is beneficial to improve the effect of oil smoke absorption, it cannot deliver fresh and clean fresh air to the kitchen, nor can it improve the combustion efficiency of the stove.

Embodiment 1

[0031] Such as figure 1 As shown, the kitchen fresh air system in this embodiment includes a range hood 1 , a range hood 5 and a ceiling 2 , and the range hood 1 includes a casing 3 and a range hood blower 4 inside the casing. The front of the casing 3 is provided with a fresh air outlet 6, and the casing 3 is provided with a fresh air inlet 21 and a fresh air outlet 6. The fresh air inlet 21 communicates with the outdoor, and the fresh air outlet 6 communicates with the room. 3. A first fresh air channel 7 connecting the fresh air inlet 21 and the fresh air outlet 6 is provided inside.

[0032]In this embodiment, the fresh air inlet 21 communicates with the outside through the second fresh air passage 13 , and the second fresh air passage 13 is located above the suspended ceiling 2 . A fresh air blower 8 , a fresh air purification device 14 and a first one-way valve 9 are installed in the second fresh air channel 13 . An air inlet 10 is provided on the suspended ceiling 2, ...

Embodiment 2

[0045] Such as Figure 6 As shown, the kitchen fresh air system in this embodiment is equipped with an oil fume purification device on the oil fume passage, and the oil fume purification device is a rear-end electrostatic purification device 20 arranged above the suspended ceiling 2 . The separation degree of grease is improved by setting the rear-end electrostatic purification device 20, thereby improving the cleanliness of exhausted oil fumes. The back-end electrostatic purification device 20 can adopt the structure of the electrostatic purification unit in the first embodiment, and the rest of the structure and working principle of this embodiment are the same as the fresh air system in the first embodiment, and will not be described here.

Embodiment 3

[0047] Such as Figure 7 As shown, the oil fume passage 5 of the kitchen fresh air system in this embodiment communicates with the second fresh air passage 13, a third check valve 18 is installed on the oil suction passage 5, and the oil fume outlet of the oil suction passage 5 It is located on the second fresh air channel 13 between the air inlet of the fresh air purification device 14 and the first one-way valve 9 . In addition, the oil fume purification device 14 is arranged on the oil fume passage between the air inlet of the range hood and the third check valve 18. In this embodiment, the oil fume purification device is integrated inside the casing 3 and located at the inlet of the range hood The front end electrostatic cleaning device 19 at the tuyere front end.

[0048] The working mode and principle of the fresh air system are as follows:

[0049] 1) When cooking, the range hood blower operates normally, the third one-way valve 18 is opened, the fresh air system is o...

Abstract

A kitchen fresh air system comprises an extractor hood and a ceiling. A fresh air outlet is formed in a machine shell and communicates with an outdoor port through a first fresh air channel and a second fresh air channel. A fresh air draught fan and a first one-way valve are arranged in the second fresh air channel. An air inlet is formed in the ceiling. An air return channel for communication ofthe air inlet and the second fresh air channel is arranged above the ceiling. A second one-way valve is arranged in the air return channel. A fresh air purification device is arranged in the second fresh air channel. An air outlet of the air return channel communicates with the part, between an air inlet of the fresh air purification device and an outdoor fresh air suction-in port, of the second fresh air channel. The first one-way valve is arranged on the part, between the air outlet of the air return channel and the outdoor fresh air suction-in port, of the second fresh air channel. According to the kitchen fresh air system, clean air can be provided into a kitchen during cooking and after cooking through control over the first one-way valve and the second one-way valve, the fresh air system enters an inner circulation mode when the outdoor environment is seriously polluted, and accordingly the kitchen air is purified.

Description

technical field [0001] The invention relates to a kitchen fresh air system. Background technique [0002] The traditional range hood only has the function of extracting oil fumes. When the range hood is turned on, it will cause negative pressure in the kitchen, causing outdoor polluted air to squeeze into the kitchen through the cracks in the door and windows, causing secondary pollution, and causing sewers, etc. Odors flow back into the kitchen, deteriorating the air quality in the kitchen. At the same time, the stove needs oxygen to burn, and the closed kitchen environment will reduce the oxygen content and reduce the combustion efficiency. If the user chooses to open the window for ventilation, he will also face the trouble of outdoor pollutants entering the kitchen and the irregular airflow outside the window disturbing the effect of the oil suction fume. . In addition, the traditional range hood cannot realize the function of purifying the air in the kitchen after coo...
