Definitions

  • the present invention generally relates to an air exchange device and, more particularly, to an air exchange device for exchange of air inside and outside of a room.
  • a conventional air exchange device 9 settled in a building's wall or the housing of an electrical product is shown.
  • the wall 91 is formed to separate an internal space and an external space.
  • the wall 91 includes an inlet 911 and an outlet 912, and both inlet 911 and outlet 912 communicate the internal and external spaces, with a fan 92 settled across the inlet 911 and another fan 92 settled across the outlet 912. Therefore, when the fans 92 operates, air in the external space enters the internal space via the inlet 911, and air in the internal space is expelled via the outlet 912. Accordingly, the air exchange device 9 can exchange air inside and outside the building cyclically.
  • the fans 92 are conventionally connected with control modules composed by driving circuits, control circuits or other electronic elements, so that the fans 92 can be driven to inwardly or outwardly guide the air.
  • control modules since the control modules tend to generate a large amount of heat during the operations, an additional cooling sink or cooling device is required to lower the working temperature of said modules. This will increase the cost of the air exchange device 9.
  • the operational noise of the fans 92 can easily transmit to the environment as noise pollution.
  • Another need is an air exchange device able to perform the air convection as well as to cool a control module.
  • a still another need is an air exchange device able to lower or shade the noise made during operation of the fan.
  • a further need is an air exchange device capable of increasing the structural strength of the divider without having to drill through holes on the divider.
  • an air exchange device which ensures that the necessary amount of area of the divider is sufficient without having to drill through holes on the divider.
  • an air exchange device comprises the features according to claim 1.

  • the control module has a housing with an opening, an auxiliary outlet, and an auxiliary inlet, the housing connects with the second end of the air-guiding tube by an edge defining the opening, and the opening communicates with the second inlet and the second outlet;
  • a board is disposed inside the housing, divides an inner room of the housing into a first branch space and a second branch space, and also divides the opening into a first section and a second section, wherein the first branch space communicates with the first section and the auxiliary outlet, and wherein the second branch space communicates with the second section and the auxiliary inlet;
  • a driving circuit or control circuit is disposed in the first branch space or the second branch space and electrically connects with the fan;
  • a light emitter is arranged inside the first branch space or the second branch space; an alarm is arranged inside the first branch space or the second
  • a "divider” is a structure adapted to separate an external space and an internal space.
  • the external space is the space outside the housing
  • the internal space is the space inside the housing.

  • the control module can also include various electronic members with function of lighting, alarm, or air-filtering, such as light emitter, alarm, and negative air ions generator.
  • the air exchange device of the preferred embodiment of this disclosure is mounted on a divider "D," with a first side of the divider “D” exposing to an external space “S1" and a second side of the divider “D,” opposite to the first side, exposing to an internal space “S2.”
  • the divider “D” has a through hole “D1” extending from the first side to the second side.
  • This air exchange device includes an air-guiding tube 1, a partition 2, a fan 3, and a control module 4.

  • an electronic member with function of lighting, alarm, or air-filtering can also be arranged inside the first branch space 41a or the second branch space 41b.
  • the electronic member is adapted to provide said function of lighting, alarm, or air-filtering, therefore, the electronic member may be a light emitter, an alarm, or a negative air ions generator.
  • the disclosed air exchange device in use of the disclosed air exchange device, only one hole, that is, the through hole "D1" in the divider "D" is necessary.
  • the airflow from the external space "S1" passes through the first inlet 111, the first air-guiding space 21, the second outlet 122, the first section 411a, the first branch space 41a, and the auxiliary outlet 412 sequentially, so as to enter the internal space "S2.”

  • first and second surfaces 11a, 11b when there is only one bent portion 113 formed between and linking the first and second surfaces 11a, 11b, they are two adjacent and non-coplanar surfaces; alternatively, if there are more than one bent portions 113, the first and second surfaces 11a, 11b, are two opposite and non-coplanar surfaces.
  • the first inlet 111 is formed in the first surface 11a
  • the first outlet 112 is formed in the second surface 11b.

Besides, maintenance or replacement of the filter 14 in the internal space “S2" can be easily performed when the divider "D" is a wall of a building.
  • the control module 4 may further include an auxiliary fan 43 aligning with the first air-guiding space 21.

  • At least one of the fan 3 and the auxiliary fan 43 electrically connects with a rotation control circuit 5, which is adapted to control the fan 3 or auxiliary fan 43 to rotate in a forward direction or a reverse direction. Therefore, when the rotation control circuit 5 controls the fan 3 or the auxiliary fan 43 to rotate in a first direction, the airflow induced by the fan 3 or the auxiliary fan 43 goes in a way shown by the arrow "I" in Figs. 3 or 6 for air convection; when the rotation control circuit 5 controls the fan 3 or the auxiliary fan 43 to rotate in a second direction, the airflow induced by the fan 3 or the auxiliary fan 43 goes in a reverse way of the arrow "I" in Figs.

  • the cover 6 comprises an inner wall spaced from the first inlet 111 and the first outlet 112 for the air in the external space "S1" to smoothly enter the air-guiding tube 1 via the opening 61 and the inlet 111, or for the air in the air-guiding tube 1 to be expelled to the external space "S1" via the outlet 112 and the opening 61.
  • the opening 61 faces downwards preferably, so as to relieve the accumulation of dust.
  • the disclosed air exchange device has advantages such as high efficiency in cooling and air-convection, long lifetime, and high degree in convenience of usage.
  • the internal space "S2" can get ride of the noise pollution due to the operational sound of the fan 3, especially when most parts of the air-guiding tube 1 and the fan 3 are outside the internal space "S2.”
