Description

Technical Field

[0001] This utility model relates to a separate range hood, and more particularly to a separate range hood system with wireless serial connection function. Background Technology

[0002] A separate design for range hoods separates the main body from the motor (or relay motor / relay fan). This allows the relay fan to be placed outside the kitchen, reducing noise generated by the motor during cooking. The main body of the range hood and the relay fan are connected via an exhaust duct to expel fumes outdoors. However, with the increasing popularity of island kitchens or open kitchens, kitchens are increasingly located in the center of the home, resulting in longer exhaust ducts to balconies or outdoors, impacting exhaust efficiency. Therefore, more than one relay fan is needed, sometimes two, three, or even more, wirelessly connected to the main body via repeaters. However, when the main body of the range hood starts, the wireless start signal is frequently interrupted by a repeater failure or network outage, causing subsequent network interruptions. This prevents the remote relay fans from starting synchronously, creating a long-standing problem for both businesses and users. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a separate range hood system with wireless serial connection function to address the shortcomings of the existing technology.

[0004] This utility model discloses a split-type range hood system with wireless serial connection function, including: a range hood body, a near-end relay fan, multiple repeaters, and a far-end relay fan. The range hood body, the near-end relay fan, and the far-end relay fan are air-connected. The range hood body, the near-end relay fan, the multiple repeaters, and the far-end relay fan are wirelessly serially connected using wireless mesh network technology. When the range hood body is started, it can transmit a start signal to the near-end relay fan and the far-end relay fan through wireless mesh network technology, thereby synchronizing the start of the near-end relay fan and the far-end relay fan.

[0005] Preferably, the remote relay fan is a common remote relay fan installed on the top of the building, and the main body of the range hood and the near-end relay fan are connected to the remote relay fan through a common exhaust pipe.

[0006] Preferably, the remote relay fan is connected to at least one other range hood body via the common exhaust pipe, and the remote relay fan can receive the start signal transmitted by at least one other range hood body via wireless mesh network technology. When the remote relay fan is operating at a first speed and receives the start signal transmitted by at least one other range hood body via wireless mesh network technology, the remote relay fan increases its operating speed from the first speed to a second speed.

[0007] Preferably, the remote relay fan includes multiple remote terminal fans connected in parallel.

[0008] Preferably, the remote relay fan is connected to at least one other range hood body via the common exhaust pipe, and the remote relay fan can receive the start signal transmitted by at least one other range hood body via wireless mesh network technology. When one of the remote terminal fans is running, the remote relay fan receives the start signal transmitted by at least one other range hood body via wireless mesh network technology, and the remote relay fan enables at least one other remote terminal fan to operate synchronously.

[0015] [Example]

[0016] Please see Figure 1 As shown, this utility model provides a separate range hood system with wireless serial connection function. The system device of this utility model basically includes a range hood body 10, a near-end relay fan 20, multiple repeaters 30, and a far-end relay fan 40.

[0017] In this embodiment, the main body 10 of the range hood, the near-end relay fan 20 and the far-end relay fan 40 are connected in an air-to-air manner, that is, the main body 10 of the range hood, the near-end relay fan 20 and the far-end relay fan 40 can be connected in an air-to-air manner through the exhaust pipe 80.

[0018] Furthermore, in this embodiment, the range hood body 10, the near-end relay fan 20, multiple repeaters 30, and the far-end relay fan 40 are wirelessly connected in series using mesh network technology. This allows the range hood body 10 to transmit a start signal to the near-end and far-end relay fans 20 and 40 simultaneously via the mesh network when it starts. Therefore, even if one repeater 30 loses connection or is damaged during signal transmission, it will automatically switch and bridge (connect in series) to a usable repeater 30. This prevents a situation where a single repeater 30's failure or damage leads to a subsequent network interruption. Even if the signal becomes unstable or is lost due to obstruction from the building's steel frame structure, walls, and floors, subsequent transmission will not be interrupted. This ensures that the signal can be transmitted normally and stably to the far-end relay fan 40, thereby guaranteeing the synchronous start of the far-end relay fan 40.

[0019] In one embodiment, please refer to Figure 2 As shown, the remote relay fan 40 is a common remote relay fan used for installation on the top of a building (such as a building with at least three floors). Furthermore, the range hood body 10 and the near-end relay fan 20 are connected to the remote relay fan 40 via a common exhaust duct 90. In other words, the range hood bodies 10 and near-end relay fans 20 on other floors can be connected to the remote relay fan 40 via a common exhaust duct 90 installed in the building.

[0020] Furthermore, the remote relay fan 40 can receive the start signal transmitted by at least one other (floor) range hood body 10 via wireless mesh network technology. And, when the remote relay fan 40 is operating at a first speed and receives the start signal transmitted by at least one other range hood body 10 via wireless mesh network technology, the remote relay fan 40 increases its operating speed from the first speed to a second speed, that is, it increases its operating speed to a higher speed, so that the large amount of oil fumes accumulated in the common exhaust duct 90 can be quickly discharged from the top of the building through the remote relay fan 40 operating at a higher speed.

[0021] In detail, when the remote relay fan 40 receives a start signal from a range hood body 10 via wireless mesh network technology, it operates at a first speed. When the remote relay fan 40 operates at the first speed and receives a start signal from another range hood body 10 via wireless mesh network technology, it increases its speed from the first to the second speed. When the remote relay fan 40 operates at the second speed and receives a start signal from yet another range hood body 10 via wireless mesh network technology, it increases its speed from the second to the third speed, that is, it operates at the highest speed. Furthermore, since the remote relay fan 40 in this embodiment is a common remote relay fan installed on the roof of a building, the maximum speed of the remote relay fan 40 is much higher than the maximum speed of the near-end relay fan 20. This effectively improves smoke extraction efficiency and avoids generating disturbing noise that affects indoor cooking.

[0022] In one embodiment, please refer to Figure 3 and cooperate Figure 2 As shown, the remote relay fan 40 includes multiple remote terminal fans 41 connected in parallel, that is, multiple remote terminal fans 41 connected in parallel constitute the remote relay fan 40. Furthermore, when one of the remote terminal fans 41 of the remote relay fan 40 is operating, upon receiving a start signal transmitted from at least one other (e.g., another floor's) range hood body 10 via wireless mesh network technology, the remote relay fan 40 causes at least one other remote terminal fan 41 to operate synchronously, that is, to cause at least two remote terminal fans 41 to operate synchronously. This allows a large amount of oil fumes accumulated in the common exhaust duct 90 to be quickly discharged from the top of the building through the synchronous operation of at least two remote terminal fans 41 in the remote relay fan 40.

[0023] In detail, when the remote relay fan 40 receives a start signal from a range hood body 10 via wireless mesh network technology, it causes one of the three parallel-connected remote terminal fans 41 to operate synchronously. When one of the remote terminal fans 41 of the remote relay fan 40 is operating and receives a start signal from another range hood body 10 via wireless mesh network technology, it causes two of the three parallel-connected remote terminal fans 41 to operate synchronously. When two of the remote terminal fans 41 of the remote relay fan 40 are operating and receive a start signal from yet another range hood body 10 via wireless mesh network technology, it causes all three parallel-connected remote terminal fans 41 to operate synchronously, that is, it causes all the parallel-connected remote terminal fans 41 of the remote relay fan 40 to operate synchronously.

[0024] In summary, the separate range hood system with wireless serial connection function disclosed in this utility model embodiment includes a range hood body 10, a near-end relay fan 20, multiple repeaters 30, and a far-end relay fan 40. The range hood body 10, the near-end relay fan 20, and the far-end relay fan 40 are interconnected, and the range hood body 10, the near-end relay fan 20, the multiple repeaters 30, and the far-end relay fan 40 are wirelessly serially connected using wireless mesh network technology. This allows the range hood body 10 to transmit a start signal to the near-end relay fan 20 and the far-end relay fan 40 via wireless mesh network technology when it starts, thereby synchronizing the start of the near-end relay fan 20 and the far-end relay fan 40. Therefore, during signal transmission, even if one repeater 30 disconnects or is damaged, it will automatically switch and bridge to an available repeater 30. This prevents the subsequent network from being interrupted due to the disconnection or damage of one repeater 30. Even if the signal becomes unstable or is lost due to the steel frame structure of the building and the layers of walls and floors, there will be no subsequent transmission interruption. This ensures that the signal can be transmitted normally and stably to the remote repeater fan 40, thereby ensuring that the remote repeater fan 40 can start synchronously.
