Description

Technical Field

[0001] The utility model relates to the field of integrated air supply, in particular to a device for realizing kitchen air supply by cooperating with a fresh air system without opening holes. Background Art

[0002] With rising living standards, range hoods have become a staple in every household. However, due to the strong suction generated by range hoods during exhaust, the airtightness of modern housing structures is becoming increasingly tight, significantly reducing the efficiency of range hoods and impacting exhaust efficiency. Therefore, supplemental air flow is necessary. Common methods include opening windows in the kitchen, creating holes in the kitchen walls, installing ventilation grilles, or adding a powered fan.

[0003] The current technology is to take in fresh air, send it indoors, and then exhaust it outside;

[0004] There is a problem of kitchen air supply. The kitchen air supply is because a range hood works, and the range hood has an air volume of more than 1,000.

[0005] If air needs to be replenished, the holes must be re-drilled. Many customers are reluctant to re-drill holes in areas with severe haze, severe sandstorms, or severe odor.

[0006] Re-drilling will destroy the integrity of the entire fresh air system, pollute the indoor air, and damage the structure of the kitchen.

[0007] Disadvantages of existing technology:

[0008] Since the kitchen range hood has a 1000m 3 The exhaust volume is about 1 / h. This will cause the indoor pressure to become negative instantly, resulting in reduced efficiency of the range hood and poor exhaust effect.

[0009] The traditional way of adding air by opening windows will remove a large amount of cooling and heating loads from each room, resulting in increased energy consumption.

[0010] The kitchen wall is drilled with holes to make ventilation grilles for natural ventilation. The amount of air supplied is very limited and will also affect the structural safety and have a serious impact on the overall airtightness of the house.

[0011] When the fresh air system is running, it is a positive pressure system, which can make the indoor air cleaner. When the range hood is working, the entire fresh air system becomes negative pressure, causing unfiltered outdoor air to seep in through door and window gaps, making the fresh air system less effective.

[0012] CN211903011U discloses a kitchen exhaust system, wherein the stove is installed in an air supply box and the exhaust hood is located above the stove. This requires too much modification to the stove, and therefore a new device is urgently needed that does not require major modifications to the stove and the current fresh air system.

[0013] The kitchen negative pressure prevention ventilation device disclosed in CN207907436U requires re-drilling holes in the kitchen.

[0014] The concepts of the prior art and the present invention are completely different.

[0015] Among them: the disadvantages of these technologies are that the changes to the stove or fresh air system are too large and require new holes to be drilled in the building. Utility Model Content

[0016] The purpose of the utility model is to provide a better device for kitchen air supply without opening holes and cooperating with the fresh air system. The specific purpose can be seen in the multiple substantial technical effects of the specific implementation part.

[0017] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0018] A device for achieving kitchen air supply by cooperating with a fresh air system without opening holes is characterized in that the device includes a shell 4, a fan 9 is arranged inside the shell 4, the outlet of the fan 9 corresponds to the air outlet 2, and more than one optional inlet is arranged on the shell 4, one of the optional inlets is connected to the air outlet of the fresh air fan 11, and one optional inlet is connected to the outdoor air outlet 18. The air outlet 2 leads to the range hood area 16, and the range hood area 16 can supply air to the range hood.

[0019] A further technical solution of the present invention is that the air outlet 2 is connected to the linkage electric valve 1, and the linkage electric valve 1 is communicatively connected to the range hood; the linkage electric valve 1 can be linked to the range hood.

[0020] A further technical solution of the present invention is that the end of the air outlet 2 leading to the range hood area 16 includes a grille.

[0021] A further technical solution of the present invention is that there are three optional inlets, which are respectively located on three sides of the housing 4 .

[0022] A further technical solution of the present invention is that the housing 4 includes an openable cover, which can be opened by hand-tightening screws 8 to repair the fan inside.

[0023] A further technical solution of the present invention is that the outdoor air outlet 18 is an air outlet when the range hood is not turned on, and is an air inlet when the range hood is turned on and needs to be replenished with air.

[0024] The present invention, which adopts the above technical solution, has the following beneficial effects compared with the prior art: when the range hood is turned off, the fresh air system operates normally, and outdoor fresh air is brought into the room through heat exchange. The indoor air passes through the heat exchange core and the exhaust duct to the outside.

[0025] When the range hood is working, the fan and the linked electric valve are turned on through the linkage of the electric control box.

[0026] At this time, the return air from the full heat exchange within the full-heat fresh air system is piped and ultimately pushed through the supply air grille to the kitchen. If the exhaust volume from the fresh air main unit is insufficient, additional air is drawn from the outdoor exhaust vent, thus achieving a high-volume supply air volume for the range hood. This innovative design utilizes the outlet duct to allow both intake and exhaust, eliminating the need for new openings in the wall. BRIEF DESCRIPTION OF THE DRAWINGS
