In the following description, embodiments of the invention are described with reference to certain embodiments of the invention. However, the embodiments described herein are not intended to limit the invention to any specific examples, embodiments, environments, applications, or specific embodiments described in the embodiments. Therefore, the description of the embodiments of the present invention is intended to be illustrative and not restrictive.

Referring to FIGS. 1 to 4, a preferred embodiment of the present invention provides a gas barrier device 100 that can be installed in an indoor unit of an air conditioning system (including an air conditioner or a cold air heater). In order to collect and exclude the condensed water W generated by the evaporator or the like (as shown in Fig. 6B), and the outdoor gas A can be prevented from entering the indoor unit (as shown in Fig. 6A). Gas barrier The device 100 can include a water collecting tray structure 10, at least one floating body structure 20, and at least one limiting structure 30. The technical contents of these elements are as follows.

The water collecting tray structure 10 may be part of the casing of the indoor unit and located below the evaporator to collect the condensed water W generated by the evaporator. More specifically, the water collecting tray structure 10 includes a water receiving surface 11 and at least one drainage channel 12, and the water receiving surface 11 can be an inclined surface, and the drainage channel 12 is disposed on the left and right sides of the water collecting tray structure 10 by taking two examples. . The drain passage 12 is a pipe body and may include a drain port 121 (the drain port 121 is formed on the water receiving surface 11 and located at a lower portion of the water receiving surface 11); thus, the condensed water W first drops onto the water receiving surface 11 Then, it flows down to the drain port 121 and enters the drain passage 12, and finally flows out from the other end of the drain passage 12 to a drain pipe (not shown) connected to the drain passage 12, and then flows out to the outside.

In addition, the water collecting tray structure 10 is also available for other components of the indoor unit (for example, a wind deflector, etc.). Since the water collecting tray structure 10 should be known to those skilled in the art, in addition to the technical contents disclosed above, the general knowledge person should be able to understand other technical contents contained in the water collecting tray structure 10, and the description may be omitted.

The floating body structure 20 takes two as an example, corresponding to the number of the drainage channels 12. The floating structure 20 is movably located on the water receiving surface 11 instead of being fixed to the water receiving surface 11, so that the floating body structure 20 can be translated relative to the water receiving surface 11 within a certain range (for example, ascending, descending, and/or traversing, etc., and translating During the process, the floating structure 20 may rotate). The floating structure 20 can be moved to the drain opening 121 on the water receiving surface 11, and since the floating structure 20 is larger in size than the drain opening 121, the floating structure 20 can close the drain opening 121, so that the drain opening 121 and the floating body structure 20 A certain degree of airtightness is achieved. When the floating structure 20 is translated to other locations, the drain opening 121 is opened (not closed). In other words, since the floating structure 20 is a movable person, it selectively closes the drain opening 121 instead of continuously and continuously closing the drain opening 121.

Further, the floating body structure 20 may be a sphere or a cylinder and may be hollow or solid with a density less than the density of the condensed water W.

The limiting structure 30 is also exemplified by two, corresponding to the number of the drainage channels 12, and is disposed on the water receiving surface 11 at a position corresponding to the drainage opening 121. The limiting structure 30 is used to define and limit the range of movement of the floating body structure 20 such that the floating body structure 20 can only move between one position of the closable drain opening 121 and another position of the openable drain opening 121. The specific structure that can achieve this effect should belong to the limiting structure 30. As shown in Figures 3 and 4, the limiting structure 30 preferably includes a wall portion 31 and a retaining wall portion 32 to define the floating body. The range of movement of structure 20.

The wall portion 31 may include three, four or more plates connected or surrounded, and a portion of the plate may be integral with the water collecting tray structure 10. The wall portion 31 is disposed around the drain port 121. In other words, the drain port 121 is located in the wall portion 31, and the lower portion of the wall portion 31 is open to communicate with the drain port 121 (the lower opening may be larger than the drain port 121). The floating body structure 20 is also located in the wall portion 31, and the wall portion 31 is larger in size than the floating body structure 20, so that the floating body structure 20 can still move within the wall portion 31. Since the wall portion 31 is vertically disposed on the water receiving surface 11, the floating body structure 20 moves vertically with respect to the water receiving surface 11; if the wall portion 31 is inclined (not shown), the floating body structure 20 also moves obliquely. In addition, the wall portion 31 may further include at least one broken groove 311 so that the inside and the outside of the wall portion 31 can communicate with each other through the broken groove 311, and the condensed water W flows in; the broken groove 311 can be located near the water receiving surface 11. If there is a gap between the plates of the wall portion 31, it also belongs to the broken groove 311.

The retaining wall portion 32 is disposed above the wall portion 31 to partially or completely close the opening above the wall portion 31 to prevent the floating body structure 20 from being detached from the upper wall portion 31 from the upper opening. However, if the shape or structure of the wall portion 31 itself can prevent the floating body structure 20 from being detached, the retaining wall portion 32 can be omitted; for example, the wall portion 31 can be a truncated cone whose lower opening is larger than the floating body structure 20 But the opening is small A convex portion is formed on the inner side surface of the floating body structure 20 or the wall portion 31 such that one of the wall portions 31 has a smaller cross section than the largest cross section of the floating body structure 20.

In another embodiment, as shown in FIG. 5 , the floating structure 20 includes two guiding blocks 21 , and the limiting structure 30 can include two guiding slots 33 , and the guiding slots 33 are disposed on both sides of the drainage opening 121 . The guide block 21 is slidably disposed in the guide groove 33. As such, the floating body structure 20 will be constrained to move along the guide groove 33, and the movement range is between the upper end and the lower end of the guide groove 33; when the guide block 21 approaches or reaches the lower end of the guide groove 33, the floating body structure 20 closes the drainage Port 121.

The mode of operation of the gas barrier device 100 will be described below.

Referring to FIG. 6A, when there is no condensed water W in the water collecting tray structure 10, the buoyant structure 20 having no buoyancy will move down to the water outlet 121 due to its own weight to close the drain port 121. In this way, the outdoor gas A cannot enter the indoor unit of the air conditioning system through the drain port 121, and the gas barrier is achieved.

Referring to FIG. 6B, when the air conditioning system is operated and the condensed water W starts to be formed in the water collecting tray structure 10, the condensed water W can provide buoyancy to move the floating body structure 20 upward and away from the drain port 121, thereby causing the drain port 121 to be Open state. In this way, the condensed water W can smoothly flow from the drain port 121 to the drain passage 12 and be discharged to the outside. The condensed water W can enter the restricting structure 30 through the breaking groove 311 to lift the floating body structure 20; in other words, the limiting structure 30 does not block the flow of the condensed water W.

Referring to Figure 6A, once the water surface 11 is again free of condensed water W (or only a small amount of condensed water W is not sufficient to lift the floating structure 20 away from the drain port 121), the floating structure 20 will automatically fall downward. It moves and is guided to the drain port 121 by the stopper structure 30, and the drain port 121 is closed again to block the passage of the gas A. In addition, the drain port 121 can be inclined with respect to the water receiving surface 11 so that The floating body structure 20 abuts against the drain port 121 to stay at the drain port 121 more stably.

In summary, by defining the translation range of the floating body structure by the limiting structure, the gas blocking device proposed by the invention can effectively prevent harmful gas from entering the air conditioning system through the water outlet, thereby preventing the gas from harming the body or the human body; In operation, the gas barrier device of the present invention does not hinder the discharge of condensed water.

The embodiments described above are only intended to illustrate the embodiments of the present invention, and to explain the technical features of the present invention, and are not intended to limit the scope of protection of the present invention. Any changes or equivalents that can be easily made by those skilled in the art are within the scope of the invention. The scope of the invention should be determined by the scope of the claims.
