Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.

Referring to fig. 1, an air conditioning apparatus 10 is provided in an embodiment of the present utility model, the air conditioning apparatus 10 being capable of being disposed in a designated space and providing air conditioning in the designated space in an operating state. Among them, the air conditioning effect includes, but is not limited to, a cooling effect, a heating effect, a dehumidifying effect, a humidifying effect, a fresh air effect, and the like. Alternatively, the air conditioning apparatus 10 may be an integrated air conditioner, humidifier, dehumidifier, air cooler, fresh air blower, or the like.

It should be noted that, the air conditioning apparatus 10 provided in this embodiment can solve the technical problem that the air outlet effect is affected by the air leakage of the water receiving disc caused by the air isolation of the water receiving disc in the prior art.

In the present embodiment, referring to fig. 2 and 3 in combination, the air conditioning apparatus 10 includes a heat exchanger 100, a first water pan 200, and a second water pan 300. The heat exchanger 100 has a refrigerant pipe 110, and the refrigerant pipe 110 may be used for introduction or discharge of a refrigerant to facilitate refrigerant circulation between the heat exchanger 100 and the compressor. The first water pan 200 is arranged below the heat exchanger 100 to receive condensed water dropped on the heat exchanger 100; the first drip tray 200 is provided with a relief hole 210 through which the refrigerant pipe 110 passes. It should be noted that, generally, the compressor and the heat exchanger 100 are disposed on opposite sides of the first water pan 200, so that the arrangement of the refrigerant pipe 110 is facilitated by forming the avoiding holes 210 in the first water pan 200. The second water pan 300 is assembled on the refrigerant pipe 110 and covers the avoidance hole 210; the second water receiving disc 300 is provided with a water outlet hole 303, and the water outlet hole 303 is opposite to the first water receiving disc 200; the water outlet 303 is used for guiding the water received by the second water receiving tray 300 to the first water receiving tray 200.

In the air conditioning apparatus 10, as described above, in order to facilitate the arrangement of the refrigerant pipe 110 on the heat exchanger 100, it is necessary to form the avoidance hole 210 on the first water pan 200 to avoid the arrangement of the refrigerant pipe 110; based on this, the second water pan 300 covers the avoiding hole 210 for avoiding the refrigerant pipeline 110 on the first water pan 200, so that the phenomenon of air leakage at the avoiding hole 210 of the first water pan 200 can be prevented, and the problem that the air outlet effect is affected due to the air leakage of the first water pan 200 can be improved. Therefore, the air conditioning apparatus 10 can solve the technical problem that the air outlet effect is affected by the air leakage of the water receiving disc caused by the fact that the water receiving disc cannot realize air isolation in the prior art. In addition, in the case that condensed water appears at a position on the heat exchanger 100 corresponding to the refrigerant pipe 110, the condensed water can be collected by the second water receiving disc 300 and then guided into the first water receiving disc 200 from the water outlet 303, which is beneficial to collecting the condensed water; that is, by providing the second water pan 300, the water leakage phenomenon at the avoiding hole 210 of the first water pan 200 can be prevented.

In this embodiment, the second water pan 300 is provided with an assembly hole 301, the refrigerant pipe 110 is assembled to the assembly hole 301, and the outer periphery of the refrigerant pipe 110 is attached to the wall of the assembly hole 301. Attaching the outer periphery of the refrigerant pipe 110 to the wall of the fitting hole 301 can improve the sealing property between the refrigerant pipe 110 and the fitting hole 301, prevent air leakage, and prevent condensed water from leaking.

That is, in the case where the second water pan 300 is assembled to the refrigerant pipe 110, the fitting of the inner circumferential wall of the assembly hole 301 to the outer wall of the refrigerant pipe 110 can close the gap formed between the assembly hole 301 and the refrigerant pipe 110, not only can prevent the air leakage at the second water pan 300; in addition, in the process that part of the condensed water flows down to the refrigerant pipe 110, it is ensured that the second water receiving tray 300 can collect the condensed water attached to the refrigerant pipe 110, preventing water leakage.

Optionally, the second water pan 300 is provided with an assembly notch 302, the assembly notch 302 extends from the edge of the second water pan 300 to the assembly hole 301 and is communicated with the assembly hole 301, and the assembly notch 302 is used for loading the refrigerant pipeline 110 into the assembly hole 301 along the radial direction of the assembly hole 301. Based on this, in the process of assembling the second water pan 300, the assembling gap 302 may be enlarged by an external force, and then the refrigerant pipe 110 is installed into the assembling hole 301 from the assembling gap 302, so that the assembling difficulty between the refrigerant pipe 110 and the second water pan 300 may be reduced, and the assembling efficiency may be improved.

The arrangement of the fitting notch 302 may be regarded as opening the fitting hole 301 in the radial direction, so that the opening size of the fitting notch 302 may be increased or decreased by the external force, and in the case of increasing the opening width of the fitting notch 302, the refrigerant pipe 110 may be caught into the fitting hole 301 from the fitting notch 302 in the radial direction of the refrigerant pipe 110; after the clamping of the refrigerant pipe 110 is completed, the external force is removed to restore the assembly notch 302 to the initial state, and the assembly of the assembly hole 301 and the refrigerant pipe 110 is achieved.

Of course, it should be noted that the second water pan 300 has a certain elastic property, so that the assembly notch 302 can be restored to the initial state after the external force is removed when the external force is increased. Alternatively, the second water pan 300 is made of a rubber material. The second water pan 300 is made of rubber material, so that the manufacturing difficulty can be reduced, and the manufacturing cost can be conveniently controlled; in addition, the rubber material is softer, so that the second water receiving tray 300 is convenient to install and detach, and the disassembly and assembly cost is reduced. In other embodiments, the second water receiving tray 300 may be made of other materials, such as a metal material with a certain elasticity; for example, other polymer materials such as plastics are used.

It should be noted that, the width of the fitting notch 302 is small, and preferably, in the case where the second water receiving tray 300 is fitted to the refrigerant pipe 110, the fitting notch 302 is in a closed state, that is, both sides of the opening of the fitting notch 302 are in a contact state.

Optionally, in some cases, when the second water pan 300 is assembled with the refrigerant pipe 110, the assembly notch 302 may be opened, and at this time, the second water pan 300 has a certain degree of elastic deformation, so that the assembly hole 301 is urged to clamp the refrigerant pipe 110 by the elastic restoring force, which not only improves the assembly stability, but also improves the sealing performance, and prevents air leakage or water leakage. Of course, in other cases, the assembly notch 302 may still be in a closed state after assembly is completed.

It should be appreciated that in other embodiments of the utility model, the placement of the assembly notch 302 may be eliminated. At this time, the second drip tray 300 is required to be installed in the refrigerant pipe 110 in the axial direction of the refrigerant pipe 110 in a case where at least one end of the refrigerant pipe 110 is a free end.

In the present embodiment, the second water receiving tray 300 includes a tray main body 310 and a fitting portion 320, the fitting portion 320 being connected to the tray main body 310; the fitting portion 320 has a tubular shape, and a fitting hole 301 penetrating the fitting portion 320 is formed in the fitting portion 320. The fitting notch 302 extends from the edge of the disk main body 310 to the peripheral wall of the fitting portion 320. The water outlet 303 is formed in the tray main body 310. Wherein, the tubular fitting portion 320 is fitted at the outer circumference of the refrigerant pipe 110, which can facilitate the lifting of the contact area between the refrigerant pipe 110 and the second water pan 300, and can prevent the occurrence of a gap between the refrigerant pipe 110 and the fitting hole 301 even in the case where the refrigerant pipe 110 is inclined, thereby improving the sealability between the refrigerant pipe 110 and the fitting hole 301.

Wherein, since the assembling portion 320 is tubular, the assembling notch 302 can be regarded as being formed of two parts, one of which is opened on the disk main body 310 to form an opening at the edge position of the disk main body 310; the other part is opened on the peripheral wall of the fitting part 320 so that the fitting part 320 can be unfolded. The openings of the two parts communicate to form the fitting gap 302 together, so that the refrigerant pipe 110 can be fitted by expanding the fitting gap 302.

In the present embodiment, taking fig. 2 as an example, in order to accommodate the number of the refrigerant tubes 110, the number of the fitting portions 320 is two, the fitting holes 301 are formed inside both fitting portions 320, and both the refrigerant tubes 110 are respectively fitted into both the fitting holes 301. Of course, in other embodiments, the number of the fitting portions 320 may be adjusted according to actual situations.

In addition, in the present embodiment, as shown in fig. 4, one of the fitting portions 320 is disposed close to the edge of the disk main body 310, and the other fitting portion 320 is spaced apart from the edge of the disk main body 310. In other embodiments, the installation position of the assembling portion 320 on the tray main body 310 may be adjusted according to the actual situation, so as to facilitate assembling the refrigerant pipe 110.

Alternatively, in the present embodiment, the inner wall of the fitting portion 320 is convexly provided with an annular sealing portion 321; the sealing portion 321 surrounds the refrigerant pipe 110. The sealing portion 321 is provided on the inner wall of the fitting portion 320, so that the sealing property between the inner wall of the fitting hole 301 and the refrigerant pipe 110 can be improved and leakage of condensed water can be prevented when the refrigerant pipe 110 and the fitting portion 320 are fitted.

In the case where the assembling portion 320 is made of a rubber material, the sealing portion 321 is pressed by the outer wall of the refrigerant pipe 110 when the assembling portion 320 and the refrigerant pipe 110 are assembled, so that the sealing portion 321 is tightly attached to the outer periphery of the refrigerant pipe 110, and the purpose of improving the sealing performance can be achieved.

Note that the formation of the seal portion 321 may be regarded as a structure formed directly protruding on the inner peripheral wall of the fitting hole 301. In some embodiments, as shown in fig. 3 and 5, in order to facilitate deformation of the sealing portion 321, an annular recess is formed at the outer periphery of the fitting portion 320, and the recess corresponds to the annular sealing portion 321, so that strength of a position corresponding to the sealing portion 321 is reduced, which is beneficial to deformation of the sealing portion 321 to improve sealing effect.

Of course, in other embodiments of the present utility model, the provision of the sealing portion 321 may be omitted.

In the present embodiment, the fitting portion 320 is convexly provided at a side of the tray main body 310 remote from the first water receiving tray 200. Thereby providing the refrigerant pipe 110 with the waterproof protection function by the fitting portion 320, and preventing the refrigerant pipe 110 from being immersed in the condensed water for a long time to cause the rust.

Of course, in other embodiments of the present utility model, the fitting portion 320 may have a portion protruding from a side of the tray main body 310 adjacent to the first water receiving tray 200.

In addition, the outer circumference of the tray main body 310 forms a burring 311 to enclose a cavity containing water. As shown in fig. 5, the height of the fitting portion 320 with respect to the disk main body 310 is higher than the height of the burring 311 with respect to the disk main body 310. Setting the height of the fitting portion 320 to be higher than the flange 311 can prevent the condensate water from penetrating into the gap between the refrigerant pipe 110 and the fitting hole 301 due to the excessively high water level in the second water receiving tray 300, and thus can prevent the problem of rust caused by the long-time immersion of the refrigerant pipe 110 into water, while also preventing the condensate water from leaking.

In this embodiment, as shown in fig. 4, since one of the fitting portions 320 is spaced apart from the edge of the tray main body 310 such that a portion of the fitting notch 302 extends to the inside of the tray main body 310, in order to prevent the problem of leakage caused by the fitting notch 302 extending to the inside of the tray main body 310, flanges 311 are also provided on both sides of the portion of the fitting notch 302.

In the present embodiment, the disk main body 310 and the fitting portion 320 are integrally molded. The tray main body 310 and the assembling portion 320 are integrally formed, so that the manufacturing difficulty of the second water tray 300 can be reduced, and the manufacturing cost can be reduced.

Optionally, referring to fig. 2, in the present embodiment, a water blocking portion 220 is disposed at an opening edge of the avoidance hole 210, and the water blocking portion 220 is supported on the second water receiving disc 300. As shown in fig. 3 and 5, the second water receiving tray 300 is provided with a water guide pipe 330, the water guide pipe 330 is disposed below the second water receiving tray 300 and extends into the first water receiving tray 200, and an internal channel of the water guide pipe 330 is communicated with the water outlet 303. By the arrangement of the water retaining part 220, condensed water in the first water receiving disc 200 can be prevented from leaking out of the avoiding hole 210; and the water flowing out of the water outlet hole 303 is conveniently and directly guided into the first water receiving tray 200 by the water guide pipe 330, so that noise or splashing of condensed water caused by water flowing out of the water outlet hole 303 is prevented.

In summary, in the air conditioning apparatus 10 provided in the embodiment of the present utility model, in order to facilitate the arrangement of the refrigerant pipe 110 on the heat exchanger 100, the avoiding hole 210 needs to be formed on the first water pan 200 to avoid the installation of the refrigerant pipe 110; based on this, the second water pan 300 covers the avoiding hole 210 for avoiding the refrigerant pipeline 110 on the first water pan 200, so that the phenomenon of air leakage at the avoiding hole 210 of the first water pan 200 can be prevented, and the problem that the air outlet effect is affected due to the air leakage of the first water pan 200 can be improved. Therefore, the air conditioning apparatus 10 can solve the technical problem that the air outlet effect is affected by the air leakage of the water receiving disc caused by the fact that the water receiving disc cannot realize air isolation in the prior art. In addition, in the case that condensed water appears at a position on the heat exchanger 100 corresponding to the refrigerant pipe 110, the condensed water can be collected by the second water receiving disc 300 and then guided into the first water receiving disc 200 from the water outlet 303, which is beneficial to collecting the condensed water; that is, by providing the second water pan 300, the water leakage phenomenon at the avoiding hole 210 of the first water pan 200 can be prevented. Further, the outer periphery of the refrigerant pipe 110 is bonded to the wall of the fitting hole 301, so that the sealing property between the refrigerant pipe 110 and the fitting hole 301 can be improved, and leakage of condensed water can be prevented. In addition, by forming the assembly notch 302 on the second water-receiving disc 300, in the process of assembling the second water-receiving disc 300, the assembly notch 302 can be enlarged through the action of external force, then the refrigerant pipeline 110 is installed into the assembly hole 301 from the assembly notch 302, so that the assembly difficulty between the refrigerant pipeline 110 and the second water-receiving disc 300 can be reduced, and the assembly efficiency is improved.

Although the present utility model is disclosed above, the present utility model is not limited thereto. Various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the utility model, and the scope of the utility model should be assessed accordingly to that of the appended claims.
