[0001] The present creation is related to a wastewater drain device for an air conditioning device, and specifically refers to a combination of a removable outlet bend pipe and an air conditioning wastewater drain pump. Prior technology

[0002] Known wastewater drain devices for air conditioning devices, such as Taiwan Bulletin No. TW I778880, disclose a conveniently assembled wastewater drain pump for air conditioning devices, in this case the lower shell has a drain outlet for water to be discharged outwards, which can be connected to a soft water pipe to direct water outward.

[0003] However, under certain needs, manufacturers of air conditioning devices will require that their drain outlets need to be set up in a certain form and specification to connect with a specific device. and that drain of the lower shell needs to take into account the mode of connection with the hard tube body and the ease of maintenance in the event of failure.

[0004] Therefore, how to connect this drain port with the hard pipe body, and also the ease of maintenance in the event of failure, becomes the subject to be solved in this case. Contents of the invention

[0005] The main purpose of this creation is to propose a combination of removable outlet bend pipe and air conditioning wastewater drain pump, which can connect the outlet pipe and extension pipe in a removable manner by means of an outlet bend pipe, thereby achieving the effect of connecting the outlet to the extension pipe and facilitating removal and maintenance.

[0006] To achieve the above objectives, this invention proposes a combination of a detachable outlet elbow and an air conditioning wastewater drain pump, comprising: a drain pump having a main housing and a lower housing; a motor is housed within the main housing; an impeller is housed within the lower housing and connected to the motor, rotating under the drive of the motor; the lower housing is assembled at the bottom of the main housing; an inlet is located at the bottom of the lower housing; and an outlet pipe extending outwards for a predetermined length is located on the side of the lower housing. Water entering the lower housing through the inlet is controlled by the impeller. Driven by the outlet pipe, water is discharged outward; and an outlet bend is detachably connected at one end to the outlet pipe; wherein, the main housing has a side wall, from which a frame extends outward, the frame having an extension pipe, one end of which is downward and the other end extending outward along the frame; the outlet bend has a transverse section and an upward vertical section extending from the transverse section, the end of the transverse section being detachably connected to the outlet pipe, and the end of the vertical section being detachably connected to the downward end of the extension pipe.

Implementation

[0009] To illustrate the technical features of this invention in detail, the following preferred embodiments are provided with accompanying drawings:

[0010] As shown in Figures 1 to 5, this invention illustrates a preferred embodiment of a detachable drain elbow and air conditioning wastewater drain pump assembly 10, which mainly consists of a drain pump 11 and a drain elbow 21, wherein:

[0011] The drainage pump 11 has a main housing 12 and a lower housing 13. A motor 14 is installed inside the main housing 12, and an impeller 15 is installed inside the lower housing 13 and connected to the motor 14. The impeller 15 is driven by the motor 14 and rotates. The lower housing 13 is assembled at the bottom of the main housing 12. The bottom end of the lower housing 13 has a water inlet 131, and the side of the lower housing 13 has a water outlet pipe 132 extending outward for a predetermined length. The water entering the lower housing 13 through the water inlet 131 is driven by the impeller 15 and discharged outward through the water outlet pipe 132.

[0012] The water outlet bend 21 is detachably connected at one end to the water outlet pipe 132.

[0013] The main housing 12 is cylindrical and has an annular side wall 121. A frame 122 extends outward from the side wall 121. The frame 122 has two frame plates 123 and an extension tube 124. The two frame plates 123 are parallel to each other and are located on both sides of the extension tube 124. The two frame plates 123 and the extension tube 124 are integrally formed. One end of the extension tube 124 faces downward and the other end extends outward along the frame 122.

[0014] The water outlet bend 21 has a horizontal section 22 and an upwardly extending vertical section 24 from the horizontal section 22. The end of the horizontal section 22 is detachably connected to the water outlet pipe 132, and the end of the vertical section 24 is detachably connected to the downwardly extending end of the extension pipe 124.

[0015] More specifically, the aforementioned detachable connection technology involves providing two outwardly extending hook arms 134 on the lower housing 13. These two hook arms 134 are located on both sides of the water outlet pipe 132. The transverse section 22 has two shoulders 224. The transverse section 22 is sleeved on the outside of the water outlet pipe 132 and is located between the two hook arms 134 and the water outlet pipe 132. The two hook arms 134 hook the two shoulders 224, thereby forming a detachable connection. If the two hook arms 134 are pushed outward so that they are not hooked on the two shoulders 224, the transverse section 22 can be moved away from the water outlet pipe 132, thus completing the disassembly. The upright section 24 of the outlet bend 21 extends outward with a locking seat 246. The frame 122 has a bolt hole 126 located on the outside of the downward-facing end of the extension pipe 124. The upright section 24 is partially inserted into the downward-facing end of the extension pipe 124, and a bolt 29 passes through the locking seat 246 and is screwed into the wall of the bolt hole 126, thereby fixing a portion of the upright section 24 of the outlet bend 21 to the downward-facing end of the extension pipe 124. As can be seen, both ends of the outlet bend 21 are detachably connected to the outlet pipe 132 and the extension pipe 124. Water discharged from the lower housing 13 flows through the outlet pipe 132 to the outlet bend 21, and then flows outward through the extension pipe 124.

[0016] To make the connection between the outlet bend 21 and the extension pipe 124 more secure, this embodiment further forms two downward-facing grooves 127 around the bolt hole 126 on the frame 122, and provides an upward-protruding convex wall 247 on the locking seat 246. When the locking seat 246 is screwed into the bolt hole 126, the convex wall 247 is embedded in the two grooves 127 to produce a positioning effect, which makes the connection more secure.

[0017] After assembly, the upright section 24 of the outlet bend 21 is separated from the side wall 121 of the main housing 12 by a predetermined distance. This design makes disassembly easier.

[0018] The structural features of this embodiment have been described above. Next, the assembly and disassembly states of this embodiment will be described.

[0019] As shown in Figure 6, during assembly, the horizontal section 22 of the outlet bend 21 is first inserted into the outlet pipe 132, causing the two hook arms 134 to hook the two shoulders 224. At this point, the outlet bend 21 is connected to the lower housing 13. Next, as shown in Figures 7 and 8, the lower housing 13 is assembled to the bottom of the main housing 12. Simultaneously, a portion of the vertical section 24 of the outlet bend 21 is inserted into the downward-facing end of the extension pipe 124. Then, the bolt 29 passes through the locking seat 246 and is screwed into the bolt hole 126 and locked. The assembly is now complete.

[0020] As shown in Figure 9, if a malfunction occurs, such as a foreign object being sucked into the lower housing 13 and jamming the impeller 15, the bolt 29 can be removed first. At this time, the outlet bend 21 can be pulled away from the extension pipe 124, and the lower housing 13 can be removed from the main housing 12. In this way, the outlet bend 21 can be removed from the main housing 12 and the extension pipe 124 while it is still connected to the lower housing 13, which makes it easier to handle the impeller 15 or the foreign object jammed in the lower housing 13. If the outlet bend 21 needs to be removed from the lower housing 13, the two hook arms 134 can be pried open so that they are no longer hooked on the two shoulders 224 (shown in Figures 7 and 8). At this time, the transverse section 22 of the outlet bend 21 can be pulled out from the outlet pipe 132 (shown in Figures 7 and 8), thus completing the disassembly.

[0021] The above-described assembly and disassembly methods facilitate maintenance and reassembly.

[0022] As can be seen from the above, the extension pipe 124 is integrally formed with the main housing 12 and the second frame plate 123. Therefore, the extension pipe 124 can be manufactured according to the specifications required by the manufacturer. However, for the sake of maintenance convenience, it is impossible to integrally form the extension pipe 124 with the lower housing 13. Otherwise, there will be problems with assembly or disassembly. Therefore, this invention provides a detachable water outlet bend 21 between the lower housing 13 and the extension pipe 124 to achieve the purpose of convenient maintenance.

[0023] The above description is merely an illustration of the present invention through embodiments and cannot be used to limit the scope of the patent application of the present invention. Any simple variations or equivalent implementations made in accordance with the scope of the patent application of the present invention and the contents of the patent specification shall be covered by the scope of the patent application of the present invention.
